You must leave this world a better place than it would have been if you had not existed.

My parents sent me to a school across town, an integrated school, where I had the chance to meet and grow up with people who were from other parts of the world. ... I remember feeling that I would never have anything to contribute on St. Patrick's Day. I couldn't tell the stories that they might have been telling about their forebears and I felt left out.

My parents absolutely did not think of themselves as part of the Great Migration. They knew they were part of a great wave. No one really talked about it in those terms or gave it a name.

There were colored and white waiting rooms everywhere, from doctor's offices to the bus stations, as people may already know. But there were actually colored windows at the post office in, for example, Pensacola, Florida. And there were white and colored telephone booths in Oklahoma. And there were separate windows where white people and black people would go to get their license plates in Indianola, Mississippi. And there were even separate tellers to make your deposits at the First National Bank in Atlanta.

That's one of the biggest losses, I think, to African American families, is that people, once they left, they turned away from the South. They didn't look back, and they often didn't tell their children about it. They didn't want to talk about it. It was too painful, what they'd gone through and the caste system of the South, which was Jim Crow.

Many immigrants do not talk about what they endured back home. They were fleeing that world, and when they left they didn't want to talk about it because there had been pain and heartbreak under the caste system of the South. They didn't want to burden their children with what they had endured.

Miles Davis, his parents migrated from Arkansas to Illinois, where he had the luxury of being able to practice for hours upon hours. He never would have been able to do that in the cotton country of Arkansas.
