A coworker from a past job once told me a story about his younger brother. He was terrified of a neighbor's house every Halloween. Not because of the decorations or display, but because of the witch mask that the homeowner wore while giving out candy. In my coworker's words, "He was so terrified of the mask, my little brother couldn't even LOOK at it." The neighbor, and owner of the witch mask, became aware of this fact and made it a point to go out of his way to follow my coworker's little brother, every single Halloween. Always ending in tears.
Man, how we'd laugh.
