The high school I went to had a strict anti-bullying policy. So naturally kids were bullied all the time. I do really think that you can't force someone to be kind. You can only change the culture around them and make it a place where kindness thrives.
I realize that changing a culture is a monumental and near impossible task. One that most people would rather not undertake. Still, there are people who do it and try to make their schools a better place.
People like, well, these, people.
