Doubt that there are bullies in school anymore, because kids nowdays spend more time in mobile, playing Minecraft, PUG or "whatever is popular now".
Better educate children not to laught on other "different" looking people (like cerebral palsy, cross-eyed, excess weight and etc).
Actually innovation of technology can be utilize by bullies to bully someone online. So yeah, it is better to educate children in doing such things that is not right. Good parenting it is!
