I only came on this for my sister, she loves Twilight just as much as I love My Sister's Keeper. This was what happened when I went to see what she was:
Me: Show me you teeth.
Sister: -opens mouth for half a second-
Me: Open your mouth, let me see all your teeth.
Sister: I'm watching a movie!
Me: This is a Twilight thing.
Sister: -pauses movie and opens mouth-
Me: -inspecting- Top canines, yes, bottom ones flat. You're a vampire!
Sister: Yes! How do you know?
Me: -explains topic to her-
I'm wierd however. I have one sharp top canine and one sharp bottom canine. The other top and bottom canines are flat. What would I be then?
