How do you prevent the bullying from occurring if you first do not know WHY someone is being bullied or are the bully? You can say don't taunt....don't belittle....don't punch, trip, beat with a baseball bat. But the bully is still a bully. The bully still hates, loathes, resents their victim of choice. The bully just knows they must be careful in their bullying. They mustn't get caught. Your method of education has done nothing to impart any type of learning on the part of the bully, just a modification of behaviour.Who cares why you were bullied, it shouldn't have happened.
That you cannot see this makes you unfit to be in any position for the care and well-being of any child; in my opinion.
