Pirate? and I went trick or treating long after most people gave it up. Even in college we were going door-to-door in awesome costumes on Halloween. Eventually we gave it up and figured we would need to have or borrow kids in order to resume begging for candy on Halloween. A couple of years ago we threw a party and decided to go reverse trick or treating.
This was easily one of the most fun Halloween activities if you enjoy making other people's day a little more surreal.
Aside from confusion, the reactions we got varied widely.
Some people were trying to eliminate their candy supply, others were delighted. Most were bemused and sort of pleased despite having no idea what was going on. It made for a good night.
