This morning BM came to drop SD (4) off for the afternoon. I could hear SD crying and BM screaming at her before they even got to my door. I opened the door and BM SCREAMS "Get to your F***ing room now". SD was hysterical and went to her room. I asked BM what happened she said that her boyfriend and her had gotten into a fight on the way over here and when she got out of the car he left. He was supposed to be taking BM to the dentist. She said SD was "being a little brat and freaking out". I told her if she needed a ride I could take her and that if she ever treated my SD like that again in my home I would be reporting it to the police. I went up to SD's room and asked her what happened. She said that her mom and BF were fighting in the car and throwing things and hitting eachother.Then BF left BM and SD was worried BM would not be able to go anywhere so she started to cry and thats when her mom got mad at her. She has welts on her arm from BM grabbing her arm so hard. WHO THE HELL DOES THAT!!!!!!! SD is 4 freakin years old and they are expecting her to not be scared when they are being insane and cant control their tempers. I just wish BM would drop off the face of this earth.She is so damn ridiculous!Her and her BF act like Jr. High kids! This is so irritating and I feel so bad that my SD has to be around that kind of trash.
