Advice if people call you names

If people call you names at school you should first tell them to please stop and if it doesn't work then you should always stay around a friend of yours and if it doesn't work then your friend could help you out and when you tell an adult that can help you out with your problem then your friend can back you up and tell the adult that what happened is true because sometimes adults don't believe you but most adults do. So if this relates to you in anyway please comment and tell me if it help and if this doesn't relate to you then comment anyways.
