Halloween fell on a Saturday that year, and by the time my mother took us to the store, all the good costumes were gone. My sisters dressed as witches and I went as a hobo. I'd looked forward to going in disguise to the Tomkeys' door, but they were off at the lake, and their house was dark. Before leaving, they had left a coffee can full of gumdrops on the front porch, alongside a sign reading DON'T BE GREEDY. In terms of Halloween candy, individual gumdrops were just about as low as you could get. This was evidenced by the large number of them floating in an adjacent dog bowl. It was disgusting to think that this was what a gumdrop might look like in your stomach, and it was insulting to be told not to take too much of something you didn't really want in the first place. "Who do these Tomkeys think they are?" my sister Lisa said. The night after Halloween, we were sitting around watching TV when the doorbell rang. Visitors were infrequent at our house, so while my father stayed behind, my mother, sisters, and I ran downstairs in a group, opening the door to discover the entire Tomkey family on our front stoop. The parents looked as they always had, but the son and daughter were dressed in costumes—she as a ballerina and he as some kind of a rodent with terry-cloth ears and a tail made from what looked to be an extension cord. It seemed they had spent the previous evening isolated at the lake and had missed the opportunity to observe Halloween. "So, well, I guess we're trick-or-treating now, if that's okay," Mr. Tomkey said.
