Bullying is when somebody is mean to you everyday. It is not if you have an argument with a friend or you fall out with someone.
There are different types of bullying:-
Physical - When somebody physically hurts you. Pinching, kicking, punching, pushing, spitting etc.
Emotional - When somebody excludes somebody, spreading rumours or lies, intimidating another person.
Verbal - When somebody says mean words, name calling, teasing.
Cyber - When somebody is mean to you online using a mobile, computer, iPad or any other device. This could be via an email, text, social media (Facebook, Instagram, You Tube, instant messaging or any other website.)
