We are all different. Some people are tall, some are short. We all have different hair colour and different colour eyes. Some people might get picked on because they are seen as 'different'. It could be the colour of their skin or because of a disability like being blind or partially sighted - or because they seem cleverer than others.
Bullying is a problem in many schools and it can take many forms.
It usually happens when someone older or bigger picks on someone younger or smaller. It can make you feel scared and upset. It can make you too scared to want to go to school. It can make you feel like there is something wrong with you and that you deserve to be bullied. Sometimes, it is difficult even to realise that you may be being bullied.
