Audio Theater

I have this really weird habit where I cannot for the life of me be comfortable if I’m any place where someone can sneak up on my while I have my head phones on/in. I know what caused this problem. I had my headphones on and I was singing like there was no tomorrow and 2 of my friends plus someone I didn’t even know where all of a sudden in my room when I turned around. I was so fucking embarrassed that I never again kept my headphones on like that unless I was sure the doors were locked. Even in my own apartment, I double lock the door because I just don’t want anyone walking up on me while I’m listening. It’s probably the fact that my back is ALWAYS to the door and I’m not facing it. If that’s the case and I always have one head phone off to listen for someone. There have been so many times where I’ve just wanted to shut my eyes and listen to music, but the thought of someone being in the same room as me just bugs the crap out of me.
