When we lived in Prairie Village, Kansas two years ago, we lived on a very small horseshoe-shaped street right off a major road with lots of traffic, so I knew we'd only get kids who lived on our street, if any. And there was only one child out of the 12 or so houses on the street, as far as I knew. She was maybe three years old, and I hoped her parents would bring her by. I left the porch light on, but perhaps because we did not do a jack-o-lantern, they did not come to trick-or-treat at the house we were renting from friends. We saw them walk by on the street and go to other houses, so we were kind of surprised, but we really didn't know them, so they were probably only going to houses of neighbors they knew. Needless to say, the candy I'd bought went into the freezer and we had to eat it!
