Bullying is when a person is picked on over and over again by an individual with more power
Both guys and girls can be bullies. Bullies may be outgoing and aggressive. Or a bully can appear reserved on the surface, but may try to manipulate people in subtle, deceptive ways, like anonymously starting a damaging rumor just to see what happens.
Many bullies share some common characteristics. They like to dominate others and are generally focused on themselves.
Some adults believe that bullying is a part of growing up (even that it is character building)
What Can You Do?
Set the record straight by telling your friends quietly and confidently what's true and not true about you.
What If You're the Bully?
All of us have to deal with a lot of difficult situations and emotions. For some people, when they're feeling stressed, angry, or frustrated, picking on someone else can be a quick escape — it takes the attention away from them and their problems. Some bullies learn from firsthand experience. Perhaps name-calling, putdowns, or physical force are the norms in their families. Whatever the reason, though, it's no excuse for being the bully.
Bullying behavior backfires and makes everyone feel miserable — even the bullies. People might feel intimidated by bullies, but they don't respect them. If you would rather that people see your strength and character — even look up to you as a leader — find a way to use your power for something positive rather than to put others down.
Do you really want people to think of you as unkind, abusive, and mean? It's never too late to change, although changing a pattern of bullying might seem difficult at first.
It takes confidence to stand up to a bully — especially if he or she is one of the established group leaders. But chances are the other students witnessing the bullying behavior feel as uncomfortable as you do. They may just not be speaking up. Perhaps they feel that they're not popular enough to take a stand or worry that they're vulnerable and the bully will turn on them. Staying quiet (even though they don't like the bully's behavior) is a way to distance themselves from the person who is the target.
When a group of people keeps quiet like this, the bully's reach is extending beyond just one person. He or she is managing to intimidate lots of people. But when one person speaks out against a bully, the reverse happens. It gives others license to add their support and take a stand, too.
