Late evening, lying on the couch. The familiar creak of the headrest, the light outside goes out. Through the wall, the kettle turns on. That sound always feels like it’s right in my own kitchen, even though I know: it’s not my tap or my mug. Over six years, the sequence barely changed — the dull knock of the kettle on the tile, the bubbling water, quick footsteps, then a pause.

Sometimes someone laughs, sometimes the bathroom light switch clicks — that sounds different, echoing through the pipes. Funny how I can remember this order more clearly than my friends’ meeting schedules. Which days the neighbor comes home late. When there’s an argument. How long the cabinet door slams after the laughter.

These sounds have settled in my head stronger than any face details or stories from someone’s real life.

It’s a strange kind of knowing. A person becomes part of your usual landscape not because they’re close — but because their life is layered by the hours of your day. I recognize moods by the tone of water in the pipes or the voice behind the wall, though I’ve never really seen this person for more than a second in the elevator.

Faces blur into half-transparent shapes. Eyes down, a distracted “hello,” the door slams — and everything goes back to the usual blind presence. This closeness without knowing is so thick it sometimes feels like we both live in the same apartment and just can’t meet in the kitchen.

The city does this automatically. In concrete walls, everyone becomes a stream of acoustic traces for others. Footsteps above — did someone change shoes? Water at night — not asleep or came home late? The hum of a TV two floors away — did the show end? Even a rare child’s cry is known as new tenants or guests arriving.

Biography details without a single word or name.

Here’s the paradox: these ties turn out sharper than formal acquaintances. Regular people pass by — you know their faces, but never noticed the rhythm of their evenings or the tone of their lives. But here it’s the opposite: the whole lifestyle reads in tiny details, but the person isn’t there. The name is forgotten right after another hallway meeting. But if a stranger slams a cabinet door louder than usual — the brain instantly sounds an alarm: something changed.

At some point, the thought hits about the other side of the game.

If I can recognize a neighbor’s life so clearly by sounds — do they hear me the same way? They must have guesses about me: what time I come home (less often than usual — probably a business trip), how I laugh on the phone (too loud?), how many minutes I spend in the shower at night (nervous or tired?). For them, my footsteps and the pauses between them also form a kind of story.

It starts to worry me — the existence of a “me” born only from the pattern of my own sound traces. Someone nearby has a whole story about me that I’ll never hear from the outside. What conclusion do they draw about me? What seems obvious to them — though to me it’s just a random part of daily life?

When one of these rituals disappears (neighbors move away or just vanish for a long time) the space inside my head changes immediately. The silence becomes thick like a down blanket right where someone else’s life used to be the background of mine. It’s not even emptiness… More like a gap in a strip of my own feeling routine.

I catch myself more and more thinking: city life is built exactly like this. You leave dozens of autobiographies around you — a sound one for some, a visual one for others, just a map of nighttime steps for a third. And you’ll never fully read any of them yourself.

Maybe the very “I” we live inside is just an echo of other people’s careful listening?
