Vampire

Well, vampires do not exist. So, it’s a fact that your addressee isn’t one. Or is he/she? Have you met him/her in broad daylight recently? When was the last time you saw his/her reflection in the mirror? Didn't he/she recently refuse to order garlic bread? Emphasis on the garlic! Anyway, a vampire friend is still a friend. Don’t you think that your friend will be happy with some thick curtains?
