I don't know what I did. I have a vague memory of doing something with my right hand from an awkward position, but I don't remember what it was, or why it didn't hurt then but really hurts now.
I've got the sliding doors open to the balcony, for the night air, and there's someone out there, probably on another balcony, with a voice like a square dance caller. It's very disconcerting. Nobody seems to realize that if you're out between the buildings, everybody can hear everything you say. I can't tell you how many "private" phone calls I've shut a window or the doors on.
