When I got back to the reservation, my family wasn't surprised to see me. There is an old Indian poet who said that Indians can reside in the city, but they can never live there. That's as close to truth as any of us can get. Mostly I watched television. For weeks I switched TV programs, searched for answers in the game shows and soap operas. My mother would circle advertisements about job in red and hand the paper to me.

'What are you going to do with the rest of your life?' she asked.

'Don't know,' I said. But I was special, a former college student, a smart kid. I was one of those Indians who was supposed to succeed, to rise above the rest of the reservation like an eagle.

For a few months I didn't even look at the advertisements my mother circled, just left the newspaper where she had set it down. After a while I got tired of television and started to play basketball again. I'd been a good player in high school, nearly great, and almost played at the college I attended for a short time. But I'd been too out of shape from drinking and sadness to be good again. Still I liked the way the ball felt in my hands and the way my feet felt inside my shoes.

At first I just shot baskets by myself. It was selfish, and I also wanted to learn the game again before I played against anybody else. Since I had been good before and embarrassed some tribal members, I knew they would want to take revenge on me. Forget about the cowboys against Indian business. The most intense competition on my reservation is Indians against Indians.

A5 The story-teller was very passive for some time. l)True 2) False 3) Not stated

A6 The story-teller never studied. 1) True 2) False 3) Not stated

A7 The story-teller served in the army. 1) True 2) False 3) Not stated

A8 The story-teller felt he was no more a strong player. 1) True 2) False 3) Not stated
