If she did that in front of you, imagine how she treats her when she doesn't have company. Her mom was just trying to help and yeah, she was being bitchy.
Her mom might have a tendency to interfere which is annoying AF (my mom does it) but it's because she dotes on her daughter and probably centers her life around hers. She could've told her to lay off gently.
You probably *shouldn't* have called her a bitch, but if you're done with the girl who cares lol. No way in hell would I consider even being friends with someone who doesn't have a basic sense of respect for other people.

Tremendous turn off. If she treats her parents like that, imagine how she'd treat you. Her mom is probably the person she's closest to on earth. She's very lucky she's not my daughter. I would have slapped that little wench so hard she'd have crossed eyes for life. I would advise never consider dating with her or associating with her. Telling either of your parents they're annoying as f*ck is really saying "I'm ready to live on my own instead of leaching off you two". That's outrageous.
