You're Too Big of a Fan When...
Your computer says "You've Got Mail" and you run outside looking for an owl.
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 get a headache after you tried 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 tons of theories to explain why that happened.
Before getting up to get something, you always try to summon it first.
You watched "Love, Actually" because two minor Harry Potter actors were in it. (Alan Rickman and Emma Thompson)
You refer to your Chemistry class as Potions.
You spend hours tapping bricks in special orders hoping that a secret entrance to Diagon Alley will appear.
You get thoroughly overexcited every time you see a word somewhere that is distantly linked with HP
You name all of your pets/children after HP characters.
You know that Harry's birthday is July 31, 1980, Hermione's birthday is September 19, 1980 and Ron's birthday is March 1, 1980 even though it never said in the books.
You went out and bought the latest editition of the Webster's Dictionary because they added the word "muggle".
Your free time on the computer is spent constantly refreshing your favorite Harry Potter news site, hoping for an update. (heehee...that's me)
