I think that I'm going to kick my roommates friend out of my car because she called me an uber
Why do you find her calling you an uber offensive?
Superfucking Uber. It's better than uber. If she wants to get out of my car and get a ride with someone else I'm okay with it.
It's understandable that you took offense to being called an Uber, however, you shouldn't leave someone stranded. Doing this will cause problems between you and your roomate. You should inform your roommates friend that you are not an Uber and that the comment makes you feel uncomfortable.
She doesn't have to apologize. I don't care about her.
I understand, I'm just saying that you should avoid fighting with your roommate whenever possible.
