Why Do Vampires Live in Mansions?

Vampires back in the day did not just like live in mansions in Georgia, like the vampire diaries. Um, they would actually live in their graves. They'd pretend to be dead and then they'd come out in the middle of the night to like suck blood before going back into their grave. And that's why the rumor that vampires are the undead. So they just don't die. And a lot of them will go back to their grave.
