Choose Your Own Hogwarts Girlfriend

Wizards and witches, lend me your ears! This Friday, Harry Potter and the Deathly Hallows, part 1 finally hits theaters! And just in time for the blessed event, I have discovered something almost as awesome as the Marauder's Map. It's a magical piece of parchment enchanted to help you choose your own Hogwarts girlfriend! Best of all, it knows how old you are (because people of ALL AGES read Harry Potter) and will age each Hogwarts student accordingly when you meet her at the Three Broomsticks!

Do you solemnly swear that you're up to no good?

Mischief managed! Who'd you choose?
