I know I sound old and you don't wanna hear this but just ignore him. Bullies just want attention to entertain them selves. Don't say anything back, just stare at them and 9 out of 10 times, this works, but if they do hit you, go Anderson Silva on them and they won't mess you anymore
it depends on what type of bullying it is but honestly try making a Powerpoint on suicide like a long one that shows its not a joke and show horrid info that is appropriate and shock everyone then bring in suicide survivors to talk about how they were bullied next bring in families of people who killed themselves and let them talk to a group of kids and anyone who is rude or disrespectful get them sent to the office and show it isnt a joke and then if all else fails take their favorite member of their family that they would hate to disappoint and tell them whats going on and that should straighten them out if that doesnt work they are souless
I'm very nearly 61 years old. Bullying was very common then. I have 5 kids, ages 37, 35, 22, 20, 18. Bullying has been happening in my kids schools over the years. I've always hated it but it just never seems to get better. It doesn't seem that we can legislate people to stop bullying.
