<human>:  I have a question about the Anti-bullying campaign. How do you define bullying?
<bot>: Bullying is a form of repeated, persistent, and aggressive behavior directed toward a victim or group of victims that involves an observed or perceived power imbalance. It can be physical, verbal, or psychological in nature, and can involve a range of behaviors, including name-calling, social exclusion, physical assault, and cyberbullying.
