It's not like I shut the door to change and forgot to open it. I never shut the door. Of course, in the middle of the night, my theory is someone wanted to rob the place, but they didn't want to wake me so they shut the door (either they're very polite robbers or they're trying to make as clean a getaway as possible). I recognize this doesn't sound too likely, but I really, really don't think clearly in the middle of the night.
I will tell you that I didn't take myself too seriously. It didn't stop me from going to the bathroom, and it certainly didn't stop me from falling back to sleep quickly. I was awake long enough to wish that someone else lived here so that I could blame it on them rather than try to figure out how and why the door ended up being shut.
I do have a special note to anyone that would consider trying to rob me. When I went to get renter's insurance, the agent was going through any "assets" I might have. By the time we were through, her assistant literally burst out laughing and said "Kind of makes you want to put a sign up that says 'Don't bother!'" Needless to say, my insurance is quite cheap.
