<human>:  Why do people bully others?
<bot>: Bullying is a learned behaviour. It is a way of establishing dominance and a way to get attention. It is often done in order to make other people feel inferior. People who are bullied often develop low self-esteem and may become depressed. Bullying is a big problem in schools today. It is important to teach children that bullying is wrong and that they should not bully others.
