And I got my unpleasant Halloween scare of the night: about 5 am, someone started turning and rattling my front door knob. I didn't want to open the door in case it was an actual malefactor, and my door doesn't have a peephole. I vaguely considered calling the cops, but I didn't really feel like dealing with them at 5am in my nightgown, and there wasn't much I'd be able to tell them "someone, who I did not see, rattled my doorknob!"
If I had been less half-asleep, I would have thought to put the chain on, and open it a bit to see who it was. I'm inclined to think it was probably some drunk guest of my neighbor's, stumbling back after a Halloween party and forgetting which door was which; it had the extended, puzzled quality of someone who really expects the door to be unlocked, not the furtive quick check of someone looking for an easy place to rob. Because it briefly happened again after I went back to bed, at which point I put my head under the pillow and went the hell back to sleep.
