BULLYING DEFINITION

We say a student is BEING BULLIED when another student, or a group of students say or do nasty and unpleasant things to him or her.

It is also BULLYING when a student is teased repeatedly in a way he or she doesn’t like.

But it is NOT BULLYING when two students of about the same strength quarrel or fight.

How often have you been bullied in school this term?
