I worked for a long time at the Tokyo branch office of the New York-based international exchange organization mainly for high school students in English-speaking and non-English- speaking countries all over the world. Those young students learn how diverse the cultures in the world are and "It's not wrong. It's not right. But it's just different." But I believe each of us must have something in common and hope it should be kept in our mind to get along with each other for a better world.
