Read the excerpt from The Land. There were other boys too who picked on me, but Mitchell was the worst. I recall one time in particular when I was about nine or so and I was reading beside a creek on my daddy's land, and Mitchell came up from behind me and just whopped me on the head. For no reason. Just whopped me on the head!
