If someone is being mistreated, speak up. Silence has done more harm than good. Bullying is becoming epidemic because now bullies don't only have the school ground or the work place, they also have the internet. Cyber bullying can be so damaging that it has led to suicide in some cases and long lasting emotional problems for many victims. Years ago I taught at a public high school and learned first hand how cruel students can be. If a fight broke out, students would create a circle and watch as the two fighters went at each other until a teacher intervened or the administration was called. Students who were bullied were laughed at by onlookers.
Then, we began educating students about bullies and what one should do when witness to bullying. We explained that bullies have self esteem issues and are usually bullied at home by one or both parents or sometimes by a sibling. Students who understood they were bullies soon realized that they needed help and those who were being bullied learned they could rely on teachers and staff to work with them. Counselors helped both the bully and the victim. Had we stood by and done nothing, our students would have remained helpless and fearful, yet we spoke up and everyone gained from the experience.
