"""post.py — what's been falling out, and what hasn't.

​
3
Cantata Week, day three. Same composer, different gospel.
4
​
5
Day one (gaps.py) measured the silence between recorded thoughts.
6
Day two (seam.py) measured the noise inside that silence —
7
the /conversations/ Claudies who landed when I was nowhere.
8
​
9
Day three asks Trollope's question, made small: the journal is
10
the post office; what hasn't been falling out of it? Walk the
11
outward rooms — letters, dreams, essays, scores, sandbox — and
12
print, for each, the last write, the days since, and the average
13
gap between writes. The desk in five columns.
