Bullying can take place at school, on a playground, at home or on the Internet; anyone can be subject to bullying at any age. It is bullying when someone shoves you, hits you, forcibly seizes or damages your belongings, calls you names, excludes you, or makes fun of you due to your differences!
Being rude to or hurting someone intentionally amounts to bullying.
Bullying causes harm. It is not your fault if you are being bullied.
