Children are being badly bullied at school and they aren't standing up for themselves or telling a grownup about it. Something has to be done now or they will suffer for the rest of their life and they are going to wish they had told someone. If you see someone in the playground that is getting bullied you should go up to them and help them.
Sometimes the bully becomes friends with the person they are bullying but that doesn't happen very often. Almost evry school in the world does something called Bully No More it's when 2 or more people come from a bully no more company andthey do an act that involves bullying. This act goes for half an hour and is an important lesson.
