I just nodded my head sideways and away, walking onward and leaving him to remember.

I'd been having some troubles with teen lads, in the last month or so — receiving taunts from groups of four or more (never from fewer, as it turns out — they're cowards.)

I went over to the window, hearing noise that sounded like trouble, for which I've developed an ear. The first kid who looked up and saw me watching down yelled "pervert" — their chosen epithet — and pulled his hoodie over his face lest I photograph him (which is where the whole business of the name-calling originated.)

I picked him out — this one, whom I just said I recognized — and I told him that I was going to make an example of him.
