Bullies bully because sometimes they have family issues, or their brothers or sisters are mean to them. They try to bully the people that are shy, or bully people that they think are weak. They don't realize how strong you actually are. They probably got bullied to. Usually bullies try to pick on kids smaller then them so it would be easier to bully because if someone they were bullying is larger then them, they would probably have a problem. They bully popular ones because they want people to be convinced that the bully has power. They also bully not so popular people because they think their weak.
