Hit back?

My girl got slapped by her classmate at school. We talked to teacher but it is not very helpful as that girl is teacher’s favourite. I was told she bully many peoples in the class but always when Teachers are not around that why nothing much was done: given that she is always very well behaving in front of the adults. Instead telling my girls to hit back, I teach them this 5 methods. 1. Look straight at the bully and question loudly to get the attention of others. 2. Warn her not to do that anymore and quick walk away. I told her not to hit back if she does (in our case) she might be the bully in the teacher’s eyes. 3. Tell her Friend(s) about the bully so that people can help her or even keep an eye on her to be her witness to tell teacher. *Remember to tell your kids to tell people be it Friend or teacher or other adults. if you tell her to tell teacher what if teacher is not around? She will be left helpless again. * 4. Tell an adult immediately when she is home. 5. Avoid playing with the bully or stay in the same place with the bully alone until she see improvement in the bully behaviours. Hope it helps. :-).
