I see a lot of possibilities in the age of my characters - between 18 and 21. You have a window of opportunity when you leave your childhood behind and have this chance to become what you always wanted to be. For me, that was a time when I could have gone many different ways. I was in flux and deciding what kind of person I would become. There's something interesting about the vision of what that will be and the reality of making that happen, and how you really are what you are. Unless you're "in character," it's impossible to get around that.
