Don't even get me started about the horrors of being addicted to drinking blood. I have no idea how you'd become a vampire, though.
I dated a girl-vampire once. Or at least she said she was a vampire. I don't know -- she said she was bitten by an el chupacabra, had really pale skin, and I swear I saw her fly once. It wasn't really a big deal because she was only about 7 or 8 inches off the ground, and it was only for like five minutes.
I met her the usual way -- at an underground vampire club. But, she never told me her secrets or showed me how to become a vampire. I miss her everyday. Apparently I was too "real" for her. Anyway, to answer your question -- no, I don't know how to become a vampire. I'm looking into werewolves now, though. The problem is they're into leather and stuff and that's....just kinda too much for me....you know? If I end up going to their rave, I'll let you all know what I find.
