Pleee hl

read this opening paragraph from "an indian father's plea" by medicine grizzlybear lake:

dear teacher, i would like to introduce you to my son, wind-wolf. he is probably what you would consider a typical indian kid. he was born and raised on the reservation. he has black hair, dark brown eyes, and an olive complexion. and like so many indian children his age, he is shy and quiet in the classroom. he is five years old, in kindergarten, and i can't understand why you have already labeled him a "slow learner."
