I am going to make it a good weekend. I am not going to be a biotch. I will be polite, but cool and distant. I will ignore her to the nth degree.
This sounds petty and childish, but it will still get her goat...I think I'm going to call my FIL and SMIL, mom & dad this weekend and if I have to address her it will be by her first name. She will HATE that.
