Yes, I feel your pain. It's hard to convince a young person of that age that something isn't real when they so desperately WANT it to be real.

Is that a little bit of Twilight I smell?

Anyway, if this young person simply refuses to listen to reason, you may just have to wait for him or her to out grow this "vampire wanna be" fad.

Until then, just make sure that they don't do anything stupid - like give out their address or phone number to any "vampires" they may meet online or drink someone else's blood (a good way to contract any number of nasty, blood-borne pathogens), etc, etc.

By the way, the person that Princess: The Feline Felon is referring to is Lord Bearclaw of Gryphon Woods (he's one of my Contacts). Hit this link to see his standard answer to any "are vampires real" questions:
