I have a friend whose b-day is coming up in on Monday and she wants me to meet her at the movies on Sunday and wants to invite some other friends as well. Unfortunately, I had to call her mother today and ask if Andrea could invite some of our other friends. In response, my friend's mother was really snotty on the phone. She was like, "I'm going to be real honest with ya. This is my daughter's day and you can't just invite your own friends along without her approval." It was like she didn't hear me and my friend wants to invite them, which she considers her friends.
To make things more complicated, my friend will be 27 but has holes in her ear drum and is Asperger's and is the only child of her parents but she acts like a 10-year-old. In addition, her parents are over protect her and spoil her rotten and have taught her to be a bit on the selfish side.
What do I do in response to her mother's behavior?
