I know you ppl have probably a;ready tried this, but I you guys should keep the notes, and show them to you guidance counselor, principal, or whoever is in charge of keeping children behaved. If they don't believe you, persist in your efforts. Try telling them why you may think they are bullying you 3. Another way to solve the prob would be to talk it over. If they hit you then that will be definitive proof they are bullying you all and if not and you have reasoned with them then you shouldn't have a prob anymore. Always remember, persistence pays of. If neither of these work contact me. If have other ideas if you need them. Hope I could be of help
P.S. I am totally crazy !!
