Something fishy is going on here. 

If your roommates don’t do something that annoys you a little bit, you’re probably living with a robot and not a real person. If you decide to cohabitate with other people, you have to get used to the fact that they’re going to do little things that you don’t like, and you’re going to do little things that they don’t like. It would be borderline impossible to find a living situation where everyone is never annoyed with each other, and if you keep trying, you’re never going to stay in one place for very long.

The most important thing is figuring out which annoyances you can accept and which you need to discuss with your roommate. If the bathroom floor is soaking wet every time they take a shower and they don’t bother to clean it up, it’s worth having a conversation about. But if they forget to take the trash out once after consistently doing so before, it’s probably best for the household if you let it go. 

This goes both ways. You shouldn’t let your roommate control your every move, because you live there too! If they have a problem with you having friends over every once in a while or freak out when you take a shower that’s «too long,» they might come from a control freak family. The roommate in this story definitely comes from one of those families. Her parents don’t want her living with a roommate, so every time they come over, she forces her roommate to either hide or pretend that she doesn’t live there.
