My main concern is that the schools might not even want to get involved, saying that this is a problem that has occurred offsite/offcampus and that parents need to deal with this sorta behavior by talking to the parents of other kids. But that really shouldnt even be an issue because these offsite actions are threatening the wellbeing of the child while at school... right?
Yeah I know that. They do this so you have to deal with yourself.
Teach your kid wait when they go away aur go quickly before they get there.
Avaoid them and not to come close to them. Leave the place when they come close to them.
