ummmm.....

ok... leave it to me to be nit-picky, but.... by your definition, most people are Vampires. What do you think gravy is?

By my definition (although maybe incorrect in the books of some), Vampires are those who desire/need/consume the blood of their own species.

...unless you're saying that Vampires are not human... in which case...

that's a whole 'nother can o' worms.
