The hour
What the clock does
A window seat lasts sixty-two minutes before noon and thirty-one after. The place did not change.
The same place at a different hour
A sitting that begins before nine runs sixty-two minutes. One that begins after one runs thirty-one. Same dwellings, same places, same people.
Sixty-two against thirty-one
The morning and early-afternoon bands, taken apart. Where the twofold difference survives, where it shrinks, and the four places it reverses.
The afternoon dip
The 13–15 band is the shortest in the record. Three explanations that fit the shape, and what the data says about each.
Why the evening band rises again
Sittings beginning after five run forty-seven minutes, longer than the early afternoon. Twenty-three observations from four dwellings, and why that is too few.
Counting a place twice, by hour
If a place behaves differently before and after noon, it may be two places. What happens to the record when it is counted that way, and why the site does not.
What the hour does to the endings
Not just how long a sitting runs, but what stops it. Each of the nine causes has an hour, and three of them barely overlap.
One window seat, five days
A single place in a single dwelling, logged across a week. The clearest view in the record of a place behaving like two different places.
The hour is not the person
A twofold difference between morning and afternoon could be a fact about dwellings or a fact about people. What separates the two, and how far the record gets.
