Why don't vampire stories have the same rules?? Lately I've been watching Buffy the Vampire Slayer -- yeah yeah I'm behind the times -- and I've noticed that these vampires don't sleep during the day, they can eat and drink, and even go into churches! And they can cut their hair and it doesn't grow back the way it was when they were made a vampire. All different "rules" from the Vampire Cronicles by Anne Rice. And there are other movies and books that follow a different set of "rules".
Which makes one wonder if one did met a vampire what would one do??
