I'm just surprised, I guess. I'm so attuned to my surroundings that it blows me away when people aren't. I'm a pest control tech; when i get to someone's house, i walk up to the front door and knock. This house today, the front door is wide open. I knock, no answer. I lean in and knock, and yell "hello", no answer. Then a guy comes to the door from inside a bedroom, wearing headphones, listening to an ipod. He didn't know I was there till I tapped him on the shoulder! He's there to install a ceiling fan, I mention that if it were me, I'd close the door. He says that's a paranoid way to think. If I'd meant him harm he'd be dead! Is this what you call a blissninny??
