You know what's really been annoying me lately? One of my roommates. Her friends in particular. One of them comes over to our apartment all the time (I won't use her real name, because I'm betting that someone here knows her). We'll just refer to her by the first letter of her name, M.

M comes over and uses our bathroom and then fails to turn off the light. I think that it is common curtesy to turn off a light when you leave a room. It save energy. It helps the environment. It keeps people like me from getting very annoyed with you. It also annoys me because I'm probably a little bit OCD.

Now, this wouldn't annoy me so much if it didn't happen quite so often. But it happens every single time she uses the bathroom. EVERY SINGLE TIME!!!! Now, energy conservation is something that I care about. I would say something to this girl, but she is way too spacey to remember. I've come very close to telling my roommate, "Tell M that if she doesn't start turning off the light when she's done in the bathroom that she isn't allowed to pee over here any more. She can use the bathroom in her own apartment." But I'm too nice.

How else can I solve this problem? I can leave little notes around, I suppose. But people don't usually like that.
