Even though, you're not giving much information. I've read this story about Wind-Wolf the name is An indian Father's Plea . Wind-Wolf is an aboriginal child that went to study to a white people's school. He was discriminated not only by his classmates, but also by the parents of his classmates. Mother of the a white child: "we don't allow those kind of people in our house!'' When my wife asked why not, the other boy's mother answered, "Because you are Indians and we are white, and I don't want my kids growing up with your kind of people." The reason why Wind-Wolf wants to leave the school. He does not feel belong to white people culture and he feels ashamed of being an aboriginal kid. This is all about racism and different culture.
