Me too, LOL. There's going to be a influx of folk demanding Harry Potter-inspired tattoos, haha.
I don't have any, but I have my wishlist. :D DH and I have always loved them and used to go to book stores and browse the ink magazines before we had kiddos. If I had the $, I'd get:
1. wedding band tat
2. script of "Esse quam videri" somewhere, wrist maybe. It's Latin meaning "To be, rather than to seem." It also happens to be my state motto, haha, but that had no bearing on the choice...
