We are referring to the text of the document called "An Indian Father's Plea" by Robert Lake, aka Medicine  Grizzlybear. This is a letter from A Native American Indian father in which he asks teachers to judge his son in a fairly way. He says that Indian children are normal, different than other children, but normal. They simply have a different history and cultural background. He adds that Native American Indians have a strong culture, tradition, and many stories to tell. And these things are interesting and Indian children can share them.
