She gestured up toward the building. She told me about the loose step on the second floor, the landlord's dog that hates Tuesdays for some reason, and that the couple in 2C argue about sports, but are otherwise fine people. That's an accurate summary. She also told me, "You make the best breakfast for dinner in the city." He looked at Ava again.

"How long have you two been talking?" Ava considered this seriously. "Since the beginning of the week. She waits for the school bus right where I walk to the train, Sophia explained, and her tone shifted just slightly, careful, not wanting him to feel like his daughter had been talking to a stranger without his knowledge. I should have introduced myself sooner.

I'm sorry I kept meaning to knock. And it's fine, Marcus said. And he meant it. He could read people well enough after 35 years to know this woman wasn't anything to worry about. She's a talker.

She finds her audience wherever she can. I am right here, Ava said. I know exactly where you are. Sophia smiled at the two of them. Well, I'll let you get to your evening.

It was good to finally meet you, Marcus. She turned to Ava. Don't forget, if you want to try that chord again, you know where to find me. What chord? Marcus asked.

Ava looked almost guilty. Almost. Sophia plays guitar. She's been showing me a little, just a little. Since the beginning of the week, he said it was two notes, Daddy.

Good night, Sophia. Marcus said in a tone that was not unkind, but was absolutely a conclusion. Sophia caught it perfectly, smiled like she appreciated the clarity, and headed up the steps. He watched her go, not in the way he'd been watching through the window, just the ordinary way a person watches another person walk away. And then he turned to his daughter.

"Two notes," he said. "They were good notes." He picked up her backpack and held the door. "Come on, birthday pizza." Her face lit up in a way that still, after 3 years of doing this alone, made everything else feel manageable.

"The birthday pizza was good." Ava talked the entire time about school, about a book she was reading about a girl in her class who could apparently do a backflip about what she wanted to be when she grew up, which this week was either a marine biologist or a chef. She was keeping her options open. Marcus ate his slice and listened and laughed where it was called for, and for a few hours, the apartment felt full in the way that it normally didn't. But when Ava was asleep and the dishes were done and the television was off, the quiet returned.

It always returned. He stood at the kitchen window with a glass of water and let himself just exist in it for a moment. Across the alley, Sophia's fire escape glowed amber in the dark. He could hear barely through the old brick walls and iron and glass the faint sound of someone playing guitar. Slow and searching like she was working something out.

He stood there listening without meaning to. It wasn't loneliness exactly. He knew what loneliness felt like. It was something quieter than that and harder to name. He went to bed.

The pattern established itself without anyone deciding it would. Sophia was on the fire escape most mornings when he was at the sink watering her plants, drinking coffee, sometimes reading something on her phone, sometimes just sitting in that particular way people sit when they're not trying to be anywhere else. She wasn't performing for him. She didn't know he was there or if she did, she gave no sign of it. He wasn't performing either.

He was just washing dishes or making Ava's lunch or standing at the window the way he had for 6 years. But now the window meant something different and he didn't fully examine why. One Tuesday morning, approximately 9 days after meeting her on the stoop, something changed. Marcus had woken up wrong. The kind of day that starts gray before it starts at all.

The anniversary of meeting Denise was coming up in a few days, and his body knew it before his brain did the way a knee knows rain. He was at the sink by 5:50, not moving, just holding a coffee mug and staring at nothing. Sophia appeared on the fire escape. She was in a gray sweatshirt, hair wrapped, not dressed for the day yet. She had a watering can, and she was moving through her plants with a kind of focused attention, checking each one, tilting her head at the leggy succulent like it had said something rude.

Marcus watched her. He didn't decide to. His brain just went quiet in the specific way that it did during the moments of the day when he stopped fighting, whatever it was, always sitting in his chest. She tilted the can over a small clay pot of something green and leafy. He watched the water run through the soil.

She moved to the next one. He watched. Then the rain that had been promising itself all morning finally started thin and cold and sudden, and Sophia scrambled to gather the small pots that couldn't take it, and she laughed at herself, actually laughed as she fumbled with the watering can, and Marcus realized he was smiling. He also realized with a slow drop in his stomach that she had looked up. She was looking straight at him through both panes of rainckled glass.

He didn't move. He couldn't reconstruct afterward why he didn't move. She tilted her head. He saw the exact moment she recognized the situation for what it was. And then, instead of closing the curtain, she slid the window open.

The sound of the rain filled in between them. She leaned on the windowsill with her forearms, looked across the alley, and called out her voice carrying easily through the wet morning air. "Okay, if you're going to stare that hard, Marcus, at least tell me, was this haircut a mistake?" She gestured at her wrapped hair with the kind of self-deprecating theater that was clearly native to her personality. He stared at her for one more second.

Then he slid his own window open and the cold rain smell came through. I can't see the haircut, he said. She pointed at her head wrap. I know, but your face says mistake. My face isn't saying anything about your hair.

Then what is it saying? He paused. It's saying I need more coffee. She burst out laughing full and real, her head dipping forward. That's the most honest thing anyone said to me in weeks.

She looked back up at him through the rain. How do you take it? Black, of course. She shook her head like this was expected. I'll be right back.

She disappeared into her apartment. Marcus stood at his open window while the cold rain wet the sill and possibly his sleeve, and he did not close it. 3 minutes later, she was back with two mugs, and she extended hers toward him across the alley in a toast, which was absurd given the 6 ft of open air between them. He lifted his mug. "Happy Tuesday," she said.

"Happy Tuesday," he said. She sipped her coffee and looked out at the rain falling into the alley. He sipped his, which was still just the one he'd made himself, but that didn't seem to matter. Your daughter told me today's a hard week, Sophia said, and she said it the way people say things when they've decided to stop tiptoeing. Direct without drama.
