It is amazing, in a disheartening way, how quckly the kids turned on each other, and how quickly they were affected by being in either group. The in group did better at their lessons, which was positive, but they were mean and nasty to the others. They all learned how it felt to be looked down on, but also how good it felt to be "on top." This was just a brief exercise; black and brown people have been considered "lesser" for centuries. It's hard not to fall into what others expect you to be when you don't have anyone telling you those people are wrong. How many lives have been lost, literally and figuratively, because of this?
