Help! DD (age 11) was on a trip when a group of her friends decided it would be funny to prank her. Water balloon in the bed which then burst and she thought she'd wet herself. One of the friends fessed up after some interrogation from her mum and apologised for being involved - the other kids have denied everything and having spoken to their parents they are sticking up for their kids (I get that). The thing is I am having a hard time being ok with these kids (not really wanting to have them round for plays and if I am honest feeling a bit disappointed in the parents) and I don't particularly want DD friends with either of them as I'm worried something similar will happen again. It's a close knit school and hard for her to actively avoid them without cutting herself out of a social group. Any advice or similar situations?
