The closure requests come in overnight. Arlo prints the queue at eight, pours coffee, works through them in order. Most are straightforward: a watcher who has seen enough, a watcher who has watched someone they loved start a life with someone new and decided this is the limit of what they are willing to carry. He processes twelve to fifteen a day. In seven years he has learned not to read too far into the names.
His sister Bea has been watching him since she died three years ago. He has felt her presence the way you feel the presence of someone standing just outside the room, the particular quality of knowing you are not alone. He has not minded it. He has cooked better since she died, kept the flat tidier. He has done things he knew she would approve of and a few things he knew she would not, and the awareness of her has been, on balance, a form of company.
He sees his own name at the bottom of the queue and sits with it for a moment before he processes it.
The form says what they all say: the watcher has elected voluntary closure. No reason is required, and none is ever given. Arlo fills in the timestamp, enters the registry number, routes the confirmation. His hands do what they always do. The coffee is getting cold.
He has thought, sometimes, about what it might feel like. The watching stopping. A door closing in a room you never saw but always knew was open. He did not expect it to happen on a Tuesday, in the middle of a queue, between a man in Glasgow and a woman in Porto who had decided to stop watching her son.
He puts the form in the outbox. He drinks the cold coffee. Outside, the street is doing what streets do at eight-fifteen in the morning, and the flat is quiet, and he sits in it and tries to locate, somewhere in the ordinary quality of the room, the precise shape of what has just changed.
