Sunday memoir confrontation 4: pass through thread characterization

That section is going to need a lot of editing—maybe a full second
draft—in addition to filling in the empirical details about
sports. But for my confrontation Sunday, it's more important that I
press onward now to the part documented by emails.

(I haven't even re-read the emails yet, as if I'm scared, as if I'm
hurt—it might be worth crediting an entire 20-minute block, not to
write, but just to read the emails following from 28 November.)
