DD says the girls she made friends with are now 'leaving her out' and running away when she tries to join them. 
I asked what she did when this happened and she said that she played with the some other friends.
I mentioned it to the teacher who said she hadn't noticed anything but this morning when we got to school, DD ran to talk to these girls and they all turned away and ignored her. This broke my heart, even though she was fine and went to line up at the school door by herself instead.
I'm probably being overly precious because I was bullied at school and can still remember how awful it felt.
