Just because he is shy and quiet in the classroom, that doesn't mean he is a "<em>slow learner</em>" like the teacher had labelled him to be. It may be that he finds it uncomfortable being among the many 'white' kids and not around his usual circle of "Red Indian" people he had been with since his birth.
