When I was completing my Harry Potter Guides I came across some of these great signs to show if you are obsessed with Harry Potter - please send me your own suggestions!
- You mutter nonsense Latin words under your breath.
- You call your least favorite teacher Snape.
- Your computer says "You've Got Mail" and you run outside looking for an owl.
- You actually ask for a broom for Christmas.
- You mutter "lumos" under your breath every time you turn on a flashlight.
- You sort everyone you meet into the four Hogwarts houses (Gryffindor, Ravenclaw, Hufflepuff and Slytherin).
- You were burned when you couldn't get through the flames of your fireplace.
- You had to go to the hospital after you broke your nose running headfirst into the wall between platforms nine and ten.
- The wand order mistake in GoF drove you crazy, and even after it was "corrected" you still came up with dozens of theories to explain why that happened.
- You point at normal things like parking meters and say "Look at the things these Muggles dream up!"
