So, all right...I've done next to no research on this, let me preface it that way. In other words, if I sound like a fucking retard or an insensitive douche, I apologize.
That said...I have a friend with some concerns about vampires that seem to have spilled over so they're now sorta my concerns. Seeing as how we all apparently come from different worlds or universes or whatthefuckever, I'm curious.
If there's good vampires roaming around here, what makes them good, who are they, and why should we trust them not to make a feast out of us? How do we tell them apart from potentially bad ones and...how does one protect one's self from those less than friendly fanged folks, exactly?
For example, it's true in my friend's world that if you don't invite them in, they can't waltz into your place and fuck you up. Is that a truth across the board or is that a rule that varies depending on where the vampire came from?
Inquiring minds want to know. Fill a dude in, guys.
