The neighbor moved out on a Wednesday. She knew this because the truck was there when she left for work and gone when she came back, and Wednesday was the only day she left before seven.
She didn't know the neighbor's name. She'd lived next to them for four years. Them — she wasn't sure if it was one person or two. Sometimes a second car. Sometimes music, faint through the wall, something with horns. She'd never knocked. They'd never knocked. The proximity was its own arrangement, comfortable in its silence, like two books on a shelf that had never been opened to the same page.
Thursday morning the driveway was empty, and something was wrong with her coffee.
Not the coffee. The coffee was fine. The kitchen was fine. The light through the window was the same July light, the same angle, the same dust in the beam. But the quality of the silence had changed. It had been a silence shared with someone else's silence, and now it was just silence, and the difference was enormous and she could not have explained it to anyone.
She stood at the window. The driveway was clean. No oil stain, no crack she recognized. She realized she'd never actually looked at it before — it had always been occupied, and an occupied driveway is just a car. Now it was concrete, thirty feet of it, and it had a quality she could only describe as recent. As if the concrete remembered being poured.
At work she tried to describe the feeling to Marcus, who shared her office. "Did you know them?" he asked. No. "Were they loud?" No. "So what's the problem?" She couldn't answer. The problem was not a problem. It was a frequency that had been removed from a chord she hadn't known she was hearing.
She drove home past the hardware store and almost stopped for something. She didn't know what. Something to put in the driveway, maybe. A plant. A chair. Something that would occupy the space the way their car had occupied it — not for her use, but for the peripheral fact of being there while she wasn't looking.
She didn't stop.
The driveway stayed empty for three weeks. Each morning she noticed it. Each morning the noticing was smaller and less like grief and more like knowledge — the kind of knowledge that doesn't help, that can't be applied, that just sits in you like a stone you swallowed and forgot about until you moved a certain way.
On the twenty-second day a new car appeared. She didn't see anyone get out. By the following Wednesday the car had been joined by a bicycle and a recycling bin, and the driveway had become a driveway again, which is to say: invisible.
She drank her coffee. The silence had changed again. It was a silence shared with someone else's silence. The chord had been repaired, but the new note was not the same note, and she was the only person on earth who knew that, and she had no way to prove it, and it didn't matter, and she would carry it anyway.
