There were a few houses near me that gave out something special in the late 80s. One house gave out baggies of home made popcorn, brownies at another, candy apples at one house, and one house took a polaroid of you in your costume. These were all beloved houses.
I'd love to do that for the younger kids in my neighborhood. But a lot of the slightly older kids that come to my door are awfully surly. They are trying to grab handfuls of candy from the bowl as you are trying to give them one, and they also steal anything else that happens to be on your front porch that night. I don't really want to deal with trying to give them something special.
