The green dress I had saved for was still waiting in Claire’s bedroom when my phone slipped beneath her couch. I reached into the tight space and pulled out something showing my own eight-year-old face. Then I spotted a note in Claire’s handwriting dated the very day we matched on Tinder—and realized she had known who I was before I knew anything about her.

My phone had vanished between Claire’s couch cushion and the armrest while she was in the bedroom changing into the green dress I had bought for her.

I muttered something I would definitely never repeat in front of my mother and shoved my hand into the narrow opening.

My fingers touched two quarters, a pen cap, something that felt unsettlingly like a fossilized potato chip, and finally my phone.

But when I pulled my hand back out, a photograph came with it.

It landed facedown on the rug.

I picked it up without thinking.

Then I froze.

The photograph was old enough for its colors to have begun fading around the edges. A group of children sat on what looked like a library floor, each one holding a book.

Near one end of the row was a skinny boy with uneven brown hair and one missing front tooth.

Me.

Eight years old, maybe nine.

I recognized myself immediately because I remembered that awful striped shirt. My mother had insisted it made me look “handsome.”

I had never given Claire a childhood picture of myself.

Standing beside me was a girl around my age wearing purple glasses.

I turned the photograph over.

Written in faded blue ink were the words:

“Nora + Ethan, Summer Reading Club.”

Underneath, in much newer black ink, were five words.

“Found Ethan today. Tell him.”

Beneath that was a date.

I checked it twice.

It was the exact date Claire and I had matched on Tinder.

A chill moved up my arms despite the warmth inside Claire’s apartment.

“Ethan?”

Her voice came from the bedroom.

I kept looking at the handwriting.

A moment later, Claire entered the living room.

The dress fit her exactly as I had hoped.

Emerald green, just as I had pictured when I went back to the boutique without her. Her dark hair was loosely pinned behind one ear, and she was still fastening the earring on the opposite side.

For a moment, she smiled.

Then she saw the photograph.

Her fingers stopped against the earring.

She never finished putting it on.

“Where did you get that?”

I almost laughed.

“Your couch.”

Claire said nothing.

I raised the photograph.

“Who is Nora?”

Her hand slowly fell to her side.

“Ethan…”

“No.” I pointed to the date. “Why did you write this on the day we met?”

She glanced toward the couch, as though some other explanation might somehow be waiting there.

At last she said, “Because I knew who you were.”

I stared at her.

“Before Tinder?”

“Yes.”

The bright green dress suddenly seemed almost absurd against the room.

“You knew me before we matched?”

“Yes.”

“How?”

Rather than answer, Claire looked at the photograph.

I read the note aloud.

“‘Found Ethan today. Tell him.’ Tell me what?”

She reached toward the back of a dining chair but didn’t sit.

“Nora was my sister.”

I looked again at the little girl standing beside me.

Something stirred at the edge of my memory.

Purple glasses.

A laugh.

A book lying open across two pairs of knees.

But every image vanished before I could grasp it.

“Your sister?”

“My half-sister. She was a lot younger than I was.”

“Why am I in a picture with her?”

Claire finally met my eyes.

“Because you were friends.”

The answer should have cleared things up.

Instead, it made everything even more confusing.

For six months, I had believed I knew exactly how Claire and I had come into each other’s lives.

I was 25 and nearly ready to quit dating apps altogether.

Claire was 45. From the very first message, she had seemed different. Direct. Funny. Completely certain about what she wanted.

The twenty-year age gap made me pause, but not for long.

Our first coffee lasted almost four hours.

She remembered that I hated cinnamon in my coffee.

I remembered that she bought awful refrigerator magnets whenever she traveled.

By our third date, she knew my boss’s name, my favorite pizza place, and how I had gotten the scar on my wrist.

With Claire, I had never felt like I needed to guess what she meant.

Apparently, I had been wrong about where she came from.

“So you matched with me because of Nora.”

Claire didn’t dodge the question.

“At first, yes.”

I placed the photograph on the coffee table.

“Wow.”

“Ethan, I wasn’t trying to manipulate you into a relationship.”

“You recognized me from childhood and never told me.”

“I know.”

“You went to coffee with me already knowing who I was.”

“Yes.”

“And I knew nothing.”

Claire closed her eyes for a moment.

“Yes. I intended to tell you that day.”

I picked the photograph back up and tapped the newer handwriting.

“You wrote this before you saw me again.”

I looked at the date one more time.

“Were you ever planning to tell me? Where was this taken?”

“The old Pine Street library.”

I frowned.

“Didn’t they gut that place years ago?”

“The original children’s room is still there,” she said. “They built around it.”

Then little fragments began returning to me.

Low bookshelves.

Beanbags.

A paper sun hanging crookedly from a ceiling tile.

I could almost smell the dusty carpet.

Then another detail came back.

Yellow.

I stared more closely at the photograph.

“Her glasses were yellow.”

Claire blinked.

“What?”

“Nora’s glasses. They were yellow.”

Claire looked down at the picture.

“They were purple.”

“No,” I said. “They were yellow.”

She studied me for a moment.

Then she laughed.

“She painted them.”

“What?”

“With yellow nail polish. My mother nearly lost her mind.”

The memory came back so suddenly that I had to sit down.

A girl sitting cross-legged in thick yellow glasses, holding a paperback far too close to her face.

I still couldn’t remember which book she was reading.

But I remembered being annoyed with her.

“You want to go there?” Claire asked.

I looked up.

She immediately realized her mistake.

“Sorry. Wrong question.”

A moment passed.

Then she tried again.

“If you want to know where the picture came from, I’ll explain it here. Or I can show you. Or I can leave.”

It was the first thing she had said all evening that didn’t sound like she had already decided what was best for me.

I grabbed my jacket.

“Take me to the library.”

Claire changed out of the green dress without saying another word.

Twenty minutes later, we stood beneath the fluorescent lights inside the Pine Street branch.

The adult section was completely unfamiliar to me.

The children’s room wasn’t.

It was smaller than I remembered.

Much smaller.

I slowly walked past the shelves until I reached the back corner.

“There used to be a blue rug.”

Claire pointed. “Right there.”

The rug was gray now.

I lowered myself into one of the tiny chairs at a little table.

My knees barely fit beneath it.

Claire stayed near the doorway.

I looked around the room.

Then I noticed a display packed with adventure books.

Another piece of memory came back.

Nora slamming a book closed.

Me accusing her of skipping three pages.

Her telling me I was simply slow.

I laughed before I could stop myself.

Claire didn’t ask what was funny.

“She cheated,” I said.

“Oh, constantly.”

“She skipped ahead.”

“Also constantly.”

“I hated that.”

“She knew.”

I looked toward Claire.

She smiled, but the smile wasn’t really meant for me.

It belonged to someone who wasn’t there anymore.

I hated how much that hurt.

“Was she sick?” I asked.

Claire briefly looked toward the doorway before answering.

“Yes.”

There it was.

The truth she had apparently been carrying toward me for the past six months.

“How sick?”

“She had a chronic condition from childhood. That summer was one of her better stretches.”

“So she came here?”

“Every week she could.”

Claire came closer but stopped on the other side of the table.

“She hated when people asked about her health before asking her name.”

I looked at the empty chair beside me.

“I didn’t know.”

“That was why she liked you.”

I gave Claire a sharp look.

“Don’t turn me into some saintly eight-year-old.”

Claire almost smiled.

“You weren’t. You made her cry once because you said she cheated at Uno.”

“Did she?”

“Absolutely.”

Despite everything, I laughed.

It lasted maybe two seconds.

Then the question I had been avoiding returned.

“What happened to her?”

Claire pulled the chair across from me.

“Can I sit?”

I nodded.

She sat down.

“Near the end of that summer, our mom took Nora out of town for specialized treatment. Everyone thought she’d be away for a few weeks.”

My fingers found a scratch carved into the tabletop.

“And?”

“She got worse.”

My thumb stopped moving over the scratch.

Claire continued in a quiet voice.

“She died that winter.”

I stared toward the shelves.

Somewhere behind us, a child laughed.

Neither of us spoke for a while.

Then I asked, “Nobody told me?”

“No.”

“But you knew I existed.”

“Yes.”

“You knew who I was when you saw me on Tinder.”

“Yes.”

“So why then?”

Claire looked down at her hands.

“Because I thought I’d finally been given an opportunity to tell you.”

I waited.

“I didn’t know your last name for years,” she continued. “I knew Ethan. I knew your mom used to pick you up in a red car. I knew you moved away not long after Nora got sick. By the time I seriously considered finding you, I had almost nothing useful.”

“But eventually you did.”

“Seventeen years later, your face appeared on my phone.”

I rubbed my palms against my jeans.

“And you swiped right.”

“Yes.”

“To tell me Nora died. That was the entire plan?”

“One coffee. Tell you who I was. Tell you what happened. Thank you for being her friend.”

I looked at her.

“And then?”

Claire gave a tired little laugh.

“Then you ordered another coffee. You stayed until they started stacking chairs around us.”

“That doesn’t explain why you lied, Claire.”

“No.”

Good.

At least she wasn’t pretending that it did.

I leaned back in the chair.

“If Nora had never existed, would you have swiped right on me?”

Claire watched me silently for several seconds.

“I don’t know.”

That hurt more than a kinder answer would have.

She continued before I could reply.

“I probably wouldn’t have stayed on your profile long enough to find out.”

I turned my face away.

“But Nora got me to that coffee shop,” she admitted. “She didn’t make me order another coffee. Or stay until they started stacking chairs around us.”

I stood up.

“What happened after that doesn’t erase what happened before it.”

“I know.”

“There you go again.”

“Sorry.”

I picked up the photograph.

“You kept deciding what I was allowed to know.”

Claire didn’t attempt to defend herself.

After a moment, she said, “Yes.”

“Why?”

“At first, because I didn’t want you to think I was using Nora to get close to you.”

“You were using Nora to get close to me.”

“To meet you. Yes.”

“And later?”

Claire stared down at the gray carpet.

“Later I was afraid you’d leave.”

That was the first answer she had given me all night that didn’t seem covered in something noble.

I folded the photograph once, immediately regretted it, and opened it again.

“I need some time alone.”

Claire stood.

“Do you want me to leave?”

I thought about it.

Then I shook my head.

“Stay here.”

She nodded.

I walked outside by myself.

And for once, Claire didn’t follow.

But halfway across the library courtyard, another memory came back.

Nora snapping a book shut.

Me furious.

My own childish voice saying:

“Fine. Finish it yourself.”

I stopped walking.

Because suddenly I needed to know whether those had been the last words I ever said to her.

I texted Claire.

“Can you come outside?”

She appeared about a minute later but stopped several feet away.

“I remembered something.”

Claire waited.

“I told Nora to finish the book herself.” I rubbed my thumb along the edge of the photograph. “Was that the last time I saw her?”

Claire slowly shook her head.

“I don’t know exactly what your last conversation was.”

Strangely, that answer helped more than false certainty would have.

“But she talked about you afterward,” Claire added.

“What did she say?”

“Mostly that you were annoying.”

I laughed.

Then Claire smiled.

“She also said you always waited when she fell behind reading.”

I looked down at the photograph.

For years, Nora had existed somewhere inside my mind as a missing piece I had stopped realizing was missing.

Now she was slowly becoming a person again.

Yellow glasses.

Cheating at games.

Skipping pages.

Getting angry with me.

I looked back at Claire.

“I believe you love me. But I don’t know what I trust yet.”

She stayed where she was.

“I understand.”

“No, you don’t. Neither do I.”

Claire nodded.

“What do you want me to do?”

The question surprised me.

“Tonight? Tell me about Nora.”

“And after?”

“I want to go home.”

“Okay.”

We spent another hour talking.

There was nothing dramatic about it.

Nora hated raisins. She wanted a motorcycle when she turned 16. She believed board-game rules were “suggestions.”

When we eventually returned to Claire’s apartment, the green dress had been neatly folded over a chair.

“Do you want me to return it?” she asked.

“No.”

Claire looked at me.

“I bought it because you wanted it,” I said. “That part didn’t change.”

Then I went home.

Four days later, I returned to the library alone and checked out the book Nora and I had once argued about.

The ending was terrible.

I texted Claire.

“Nora was right. The ending is awful.”

Her reply came almost immediately.

“She was unbearable when she was right.”

I smiled.

“I’m still at the library if you want to come argue about it.”

Claire arrived 20 minutes later.

We sat together at the same small children’s table.

As I read, her hand instinctively moved toward the page.

I placed one finger down.

“Hey. I’m not done.”

Her hand stopped.

“Sorry.”

She pulled it back.

And waited.

I finished the paragraph.

Then I turned the page myself.
