People expect vampires to be drawn and pale, so I will use cosmetics to make myself look like a sun-worshipper. If having a widow's peak is part of vampirism, I will do my best to disguise that fact with an appropriate and flattering hair style. I shall immediately purchase a Hooked on Phonics tape, in order to lose any Romanian accents I may have. If I can manage it effectively, I will instead affect an accent that people don't normally associate with vampires, such a Liverpool Scouse or Appalachian. My transportation will emphasize utility over style and must fit into the local surroundings.
People expect vampires to be rich, glamorous, and reclusive.
It's hard to think of a guy who goes to PTA meetings as being a blood-sucking fiend. I will volunteer at the local hospital or Red Cross blood center. I will invest in a modern state of the art security system, including barred windows and doors, deadbolt, pass-coded locks, and an electric alarm system that is hooked into the local police station. If I am capable of turning into mist, my inner sanctum and several escape routes will only be accessible by people who are capable of turning into a gas. If I am capable of flight in any form, I will have at least one entrance to my lair, and one escape route, which is only accessible by people who are able to fly or float.
