"Everyone is angry when they lose someone. But in Africa, in Matobo, it's different. To stop sadness, you must save a life. That's what the Ku believe. When someone is murdered there's an all-night party one year later, next to a river. In the morning, the dead man's relatives bring out the killer, tie him up, and put him in a boat. They take him out onto the water and throw him in. He can't swim. The family can watch him die, but they will always be sad. The act of saving him will take away their sadness. They will realize that life isn't always fair." She stopped for a few seconds, and then she said, "It's too easy to take a life." She pointed at the photo. "That was a long time ago. I 'm leaving. I have a class."
