I mean... there is a reason vampires seem like an exaggerated version of us... vampires come from the scary stories told to the other villagers about the weird "introvert" that hadn't been forced by anyone to "live a normal life". That person must be crazy or some kind of monster. I can't even imagine what they must be doing in that creepy house all alone. Turns out, thriving. And hiding, from all the people that have scared themselves to the point of taking it out on the person that is hiding from them. "What reason do you have to hide from us if you aren't a monster?" Self-fulfilling vicious circle...
