I also had similar nightmire, quite a few times actually. I wonder if every mother has this?

I figured it out, don't worry :) You are lucky to have your neighbors as your LJ-friends...

400 trick-or-treaters -- incredible! We only had maybe two dozens of them. It was actually quite silent this year, not much fun. Siren at 6pm - about two dozen kids come - siren at 8pm at the end... That's all. I feel sad about it a little :)
