As horrible as bullying is, some people will continue to bully others because they find pleasure at making others suffer. One person was sitting on a public bus when they noticed three school girls were bullying another school girl because of her size. They grabbed her lunchbox and emptied out all of her food outside the window.
The girl was visibly upset but couldn’t do anything, so she went and moved herself. The girls continued to harass her until one kid had enough and gave one of the bullies a taste of her own medicine.
