just a thought....if somebody is knuckleheaded enough to be bumping around while robbing my house in the middle of the night, he has already failed in his endeavor. if he's silent, he must be good, and i guess he's earned my stuff. otherwise he will be actively hunted. offense is the best defense. my house is small, and i'm quite sure i could easily determine where the noise was coming from. i would splash some deer park on my face, listen closely for a few seconds and silently proceed. i myself can't abide the thought of sitting around being taken advantage of. i don't really buy into the idea of it not being smart or safe to leave my room. what's not smart or safe is trying to break into my house and steal my stuff.
