Then, when it had finally rolled off, I counted the buttons on the coats over again, eight on one, eight on another, ten on the third, and compared the lapels once more; my voracious eyes touched, caressed, embraced all these ridiculous, trivial details with a hunger I am unable to describe.
This is the only context (well not only, but definitely one of them) where I’m ok with someone remembering absurd details (unlike EoV)
Also it’s a bit weird he’s sharing all this with a stranger. But perhaps he hasn’t been out long and needs to company?
