  13. I gave away tea bags, popcorn, apple cider, and hotel coffee packets the first year I moved into the neighborhood where trick-or-treaters flock like Hitchcock's Birds...I was not ready! Every time I started to shut the door, and turn off my porch light, there was already a new flock coming up to my door! Scary times.
