What do other people think?
Believe it or not, there are often serious underlying issues that cause a bully to target someone. While these causes are not justification for a bully's actions, they do shed some light on why these people pursue violence and power over someone. Is someone currently bullying you at school or work? If so, here are some of the causes of your bully's behavior.
The one who teases others is “the boss.” He can then take this behavior and solidify his standing when he spreads rumors about girls, sneers at someone as they walk down the hall and jabs at his buddies to do the same, when he insults people. Then, if the person reacts with a sense of embarrassment or hurt, he puffs up a bit more in the chest. He feels a little stronger, maybe more popular, because he has affected the person in a negative way, and his friends probably went along with it. Which by the way, means they aren’t that person’s friends.
