My fiancee has that creepy quality too. I got home yesterday, opened the door, turned around facing the living room to lock the door, and out of the corner of the door (against the wall) in his best creepy voice, I hear him say Hi. I screamed and nearly hit the ceiling. I didn't even see him until he said that. On the plus side, since he knew he was going to terrify me to almost death, he brought me a vodka tonic .
