" There was a date beneath the image: 1955. I realized that Mother had been four years old in 1955, and with that realization, the distance between me and Emmett Till collapsed. My proximity to this murdered boy could be measured in the lives of people I knew. The calculation was not made with reference to vast historical or geological shifts--the fall of civilizations, the erosion of mountains. It was measured in the wrinkling of human flesh. In the lines on my mother's face. "
