Friend A has been hitting some of the girls in their group with a plastic file, sometimes it was in a joking way, other times it was because she didn't like what was said. Another friend B of hers chose told me the same thing and she didn't like it as she felt the girl was taking the opportunity to hurt her rather than having a joke. Also, friend C was pushed against a wall by A last week and hit with said file, friend A keeps taking pens off her in lessons and generally being mean to he. She threatens them with her brother if she doesn't like what they say and pushes them off their seat if she can't sit down.
Last night my daughter walked home with A and another girl. They were joking about something and the other girl said, hit her for me which A did with an umbrella causing a raised red mark on about 40% of her hand which started to go down 30 mins after she came home. My daughter acknowledges it was originally a joke but she feels A has taken the opportunity to hurt her while she has the opportunity. My daughter doesn't want to raise it at school as they are quite a argumentative group and you never know who will be ousted out.
My husband thinks we should raise it, as he feels A shouldn't be hitting someone that hard and neither of us like what she's done to friend C.
Would you see how it goes for a few days, or should we alert the school in the hope they are more likely to listen if someone reports A.
