There are always houses you don't visit.
Houses with no porch lights are generally avoided on Halloween night. You expect fun tricks from well-lit domiciles, but nothing mean or nasty.
When I was eight or nine, I went trick-or-treating to a well-lit house. Halfway up the jumblied sidewalk, the porch lights went out. In the sudden darkness, I fell. Sharp pain lanced my palms and I found myself picking thumb tacks from my hands. Crying, I went back to the car and showed my mother. We left and never returned to that house.
