Bullying is behaviour that hurts someone else. It includes name calling, hitting, pushing, spreading rumours, threatening or undermining someone. It can happen anywhere – at school, at home or online. It's usually repeated over a long period of time and can hurt a child both physically and emotionally. Cyberbullying is bullying that takes place online. Unlike bullying offline, online bullying can follow the child wherever they go, via social networks, gaming and mobile phone.
