CyberBullying

I don't understand cyberbullying very much becuase I don't see it that much. But I also don't understand why others would try to ruin someone's life. Because thats what they do at this age. And just thinking about someone not wanting to live anymore because of the horrible things they say to them is just wrong. I don't get it. They should just stop because the targets for bullying usually have other bad things going on on their lifes.
