I'm home after our robotics meeting, handing out candy and working on homework.
My desk is situated by a window from which I can see my driveway. As Trick-or-Treaters walk past the cars, I set off the panic-alarms on them from inside the house - it gives them a pretty good scare.
EDIT: The trick-or-treaters have stopped arriving, at least for the last hour or so. The last group came at about 7:57, and the North Brunswick curfew was at 8 o'clock.
