I'm going to make my girlfriend's roommate uncomfortable by staying over a lot
Why do you want to make her uncomfortable?
She's just being annoying and ignorant. I want to hurt her
I understand that some people can be annoying. But if someone makes you feel uncomfortable just because they find you annoying, wouldn't you feel the same?
If it was that easy, I'd have done it already.
It is immoral to make someone else feel bad in their own home. You should be a courteous guest and respect their space, not make conflict.
