My last year was in high school. We filled our buckets with candy that we purchased ourselves, and then ran around the neighborhood "restocking" all the houses after yelling "Trick-or-Treat!" We'd accept and immediately eat one piece of candy each from anyone who offered, and one of us would ask, "what do we say?" and we'd all shout "thaaank yoooooouuuuu!" with candy in our mouths.
