Sherman Alexie said this quote

“ For the mentally disturbed, Marie knew these sandwich visits might be the only dependable moments in their lives. She also knew she delivered the sandwiches for her own sanity. Something would crumble inside of her if she ever walked by a homeless person and pretended not to notice. Or simply didn't care. In a way, she believed that homeless people were treated as Indians had always been treated. Badly. The homeless were like an Indian tribe, nomadic and powerless, just filled with more than any tribe's share of crazy people and cripples. So, a homeless Indian belonged to two tribes, and was the lowest form of life in the city. The powerful white men of Seattle had created a law that made it illegal to sit on the sidewalk. That ordinance was crazier and much more evil than any homeless person. Sometimes Marie wondered if she worked so hard at anything only because she hated powerful white men. She wondered if she went to college and received good grades just because she was looking for revenge. ”
