that and i think for me it was so obvious when i looked at -- this story, harper lee was bon in monroeville but the temperature takes peninsulas in a town called alexander city and when i go there it's a mill town and people who live in and work there if they don't work for the mill, they're parents did or grandparents did and it was a mill town mechanized by hydroelectric power and port of the story is-the-way watershed changed and mills mechanized by hydroelectric power. you can not talk about the money and affluence of the community or ongoing exploitation of black work notices worked the nine in the mills unless you explain how the profit structure word and what changed live and why there are up toes of this size. love history and i do think it's the way we make sense of the world and i think to some extent harper leave agreed with that, part of what she is doing and marking birder is tellogy how people in make come relate to each other because of how their parents related to each other and who is allowed to change or evolve and who isn't, and who is in control of the way society works.
