Bullying is not fair at all as it can damage a persons social life for a long time, even a few years or even forever. While it can sometimes make the bully feel better, it can make the victim feel terrible and end in feelings like depression and anxiety. It can cause problems with developing healthy social connections for years after the experience of bullying.
Causes of Bullying
Bullying is often caused after the person who is bullying is hurt them self (Someone being horrible to them).
