Hallow-e'en or Hallow-Even is the last night of October, being the eve or vigil of All-Hallow's or All Saint's Day, and no holiday in all the year is so informal or so marked by fun both for grown-ups as well as children as this one. On this night there should be nothing but laughter, fun and mystery. It is the night when Fairies dance, Ghosts, Witches, Devils and mischief-making Elves wander around.
