Those sound like familiar behaviors to me!! My mom blames everything in her own life on her mother, but then takes no responsibility herself. I told her that if she can blame things on her mother, then I should be able to blame things on her. LOL. That didn't go over very well.
When my mom was better, she would also OCD move things in my house. It was an annoying habit.
That stuff where she is comparing your son to kids where she works sounds very inappropriate!! It's rude for her to say that and ridiculous. I can see why it would make you upset.
I'm glad you were able to get some time with your friends!
