I've been Miss Lunatic in my head for so long that I get confused when I see my actual last name. There was a time in high school that I felt similarly, but then I had no other name to replace it with. More and more I'm starting to feel that $FIRSTNAME $LASTNAME is a convenient social/business formal mask that I put on. The more I step into Miss Lunatic, the less well Miss $LASTNAME fits. I rather prefer being Miss Lunatic.
There are all sorts of uncomfortable things about one's blood kin, and I'm struggling with some of them right now.
