We live in a family friendly neighborhood, with houses built in the 1920s and 1930, with lots much deeper than they are wide. Consequently, we get a lot of Trick or Treaters. Hundreds of them. Our 80-year-old house has one of those mail slots, where the mail falls onto the entryway floor. Just the thing for Halloween.
I love seeing their startled expressions through the slot. He he he.
