In my world:

Vampires don’t sparkle.  But they do eat pizza.

All blood is life.  Squirrel blood is gross.

Death by stake, sun and silver bullets.

They are fast.  They have O.C.D.

They are not demons.  That doesn’t mean they’re not evil.

Visible in mirrors, sensitive to garlic, unaffected by crosses.

Hypnotic, but not omnipotent.

Sexual.  Aggressive.  Jealous.
