My SD BM is driving me crazy. She's 27 years old and acts like she is 10 !! I called her about a week ago because my SD was getting in trouble at school . And i figured that it has something to do with all the fighting and things that are going on. So trying to be the adult in the situation and called to talk to her but I didnt have the notes that i needed so she said that she would call me back the next night . SHE DIDNT. My husband was then talking to her on Saturday and asked her why she had not called me back she said she was busy. So then my SD is sick on Monday i work for a DR.
