Oh MAN!!!
The thing is that they get along great UNTIL this one part timer 6 yrs old comes. Then the whole dynamic changes and it's one argument after another and she is the root of every problem!!!! I had such an issue with her bullying when she was here for after school care, that I flat out told Mom that I would not be tolerating this behaviour over the summer, and that July will be her month of probation. Mom and Dad must have laid down the law (finally) at home, because the rest of her school year went great. Her first full day here for the summer though...not so great. It's honestly just bitchy behaviour! Never towards me, but she's SO argumentative with the other kids, it's ridculous!!
