I would ask him how old is he and how's his vampire wife. Then I would tell him that my best friends are Blade and Blood Rayne so he better tries not to do something wrong...
i would try to run but i will not be able to cause i will be afraid.he will chase me,he will bite,me i will become a vampire,bite all you in that topic,now you are vampires and this is a happy end.
Uhm.. I would ask him if he/she's high because vampires' eyes are usually red. And if I would find out that he/she is, I would report him/her to a police for an immediate and accurate action.
Haha I would figure out some stuff about him first, then I'd either kill him with his weaknesses, or become a friend. You don't even wanna know what I'd do if he tried to bite me! ( :
