One afternoon, the Delany sisters sit in the living room of their red brick house in Mt Vernon, N.Y. Their memories a held in common, and their voices jockey for position as they recall their childhood in Raleigh, N.C., and their father, a former slave who became America’s first black Episcopalian bishop. Did their father sit at the head of the table? Sadie: “Oh, yes.” Bessie: “And we had three squares a day! And we always said grace!” Sadie: “Always. Yes, indeed.” And their mother?

And she opens her eyes and says, ‘Oh, Lord, another day?!”’ Here’s hoping there’s many more.
