Sunday moring in the park with the kids and I hear- 'come here you little twat'! I look round and see this young girl talking to her 2 yo (guess) son! COuldn't believe t. My 2 dss hear her foul mouth too and I didn't even think about it and said 'excuse me' SHe pulled her face and said 'yeah' in a real attitudey way. 'Can you watch your language please'. She gave me a filthy look and I thought I was gonna get my head kicked in, grabbed her son and 'threw' him in the buggy and he understandably started crying. It must have hurt his back or neck by the way she forcefully did it.I felt sooooo sorry for him and wanted to grab him and run away. Then she shouted to her little girl who looked around 3yo,'hurry up im gonna leave you here' and with that walked quickly out of the park and away from her little girl. The poor thing was crying and ran after her. Then her foul mouth shouts to the girl 'what the fuck do you think you were doing you little fucker'. OMG I was mortified and sat there thinking what can I do for them - nothing was the answer. No one could convince me that staying with their bio mother is the best thing for them, they should be given the chance to start a new life with a loving family.Away from this abusive, bully of a mother.If she acts like that in public what goes on behind closed doors? I hate seeing things like this and I cant get it out of my mind. Was I right to say something? Should I have done more?
