Bullying most often occurs in classrooms and playgrounds at school. It involves psychological, verbal, or physical abuse that is repeated over time. The most common type is emotional abuse. Bullies are often children entering adolescence between 12-13 years old, and can be boys or girls, though boys tend to bully more. Children who are bullied may exhibit low self-esteem, passive behaviors, and lost interest in school, which could lead to academic failure, emotional issues, and even suicidal thoughts. It is important to reject bullying and not become part of suicidal behavior.
