The tale of how candy tastes scary to me.
Most of the time, candy is not the kind of reward kids think of when presented a conditional situation. Throughout the year, they are promised and granted toys, experiences, and allowances for their good behavior, good grades, and overall goody two-shoes persona. Halloween comes along once a year and negates all the virtue and instead rewards you with the vices of all flavors, shapes, and sizes. You dress up as the nightmares of your imagination, maybe as the ones that frighten you the most, like the Batman does, and face your fears by mocking it in costume. But I do not object to a sexy Headless Horseman or Bearded Lady (can you imagine the necking? Horrific!). Halloween has a lasting effect, more than for its annual ceremony, that stays behind long after the night is out.
