Building your own traditions is a solid part of a relationship! Halloween is my youngest daughter's favorite holiday, as well. Every year I wait anxiously to hear what her Halloween costume is going to be. Her twins were 4 months old this past holiday, and one was a pineapple and one an avocado! Too funny. One of my favorites has been when she went as Elaine from Seinfeld and her friend went with her as Kramer. (The parking garage episode!)
