The SK go back to BM's today. The two oldest were up before my BK to say goodbye to their dad before he left for work and do a few chores. Choosing chores resulted in the SK's physically getting into a fist fight. The oldest punched the younger one in the stomach. SO dealt with it with making them apologize and give hugs but the act of defiance and attitude towards their dad was unbelievable. The worst I have ever seen. The older one is suppose to go ocean fishing with his grandparents the next time here. If it was my kid he wouldn't be going with that attitude!!!!! Hoping the next visit goes better behaviourwise.
