My Thoughts On Bullying

I've witnessed someone get cyber-bullied. I see it on twitter, facebook, instagram, youtube etc. I would tell them to stop but no one ever listens anyways they're still going to keep bullying. It would matter to me if my close friends and family got bullied that's when I'll actually say and do something. At times i will defend the person getting bullied, but i wonder if i ever got bullied would anyone step up for me if i couldn't. I don't think I've ever seen someone get bullied physically, but if i did i would say something. I think that bullying will never go away because of all the social medias. Plus everybody is just so rude and just care about themselves. It's possible a bully can stop being a bully if they got bullied as much as they bully other people. I wonder if teachers actually care about bullying like if they would see someone get bullied would they do something or just walk back into their classroom and act like they never saw anything.
