It's just my girlfriend and I in our rowhome. Since the nights are beginning to get hot, our AC gets turn on. When the nights are cool, we usually leave the bedroom door open to hear if someone breaks in or whatever. Well, with the AC running, you can't hear a damn thing and having the door close is even worse. I'm paranoid like that. I have a 9mm under the bed, but i guess i wouldnt be able to react. Well, my friend suggested I lock the door. I never liked the idea cuz I always think of "what if." Maybe I should do it tonight.
