We never get any Trick or Treaters in our building. I don't even bother to buy candy anymore (except for myself--I love candy corn!)
The place where I live is on a cul-de-sac that ends at a steep slope covered by trees. You can't see the building from the corner because of the dark wooded lot next door. To a kid, I suppose it would look pretty spooky. Having seen a lot of spooky movies, I can understand that feeling.
Have a nice Halloween and remember to Fall Back your clocks tomorrow!
