Two friends have an argument that breaks up their friendship forever, even though neither one can remember how the whole thing got started. Such sad events happen over and over in high schools across the country. In fact, according to an official report on youth violence, "In our country today, the greatest threat to the lives of children and adolescents is not disease or starvation or abandonment, but the terrible reality of violence". Given that this is the case, why aren't students taught to manage conflicts the way they are taught to solve math problems, or stay physically fit?
A report on violence among high school students indicates that most violent incidents between students begin with daily small matters such as a relatively minor insult (侮辱). For example, a fight could start over the fact that one student eats a peanut butter sandwich each lunchtime. Laughter over the sandwich can lead to insults, which in turn can lead to violence. The problem isn't in the sandwich, but in the way students deal with the conflict.
There will always be conflicts in schools, but that doesn't mean there needs to be violence. Learning to resolve（化解）conflicts can help students deal with friends, teachers, parents, bosses, and coworkers. In that way, conflict resolution is a basic life skill that should be taught in schools across the country.
