A Thought

Why is it that bathroom doors typically have locks, but bedroom doors don't? I understand that when you're in the bathroom, you want privacy, and you're vulnerable. You're either going to the bathroom or in the shower, most likely. However, in the bedroom, you're asleep, which is even more vulnerable of a position in which to be.

Also, the bedroom is where you keep most of your valuable stuff. A computer, your wallet, pretty much anything you spent a lot of money on that isn't a TV is in your bedroom. But you don't get a lock to protect it, or protect yourself whilst sleeping. But if you want to poop with impunity, the bathroom is well protected.
