I grew up in the segregated South. I tell students the story of how, as a young boy, I went with my mother to Bloomberg’s Department Store on High Street in Portsmouth, Virginia. There was a stack of doilies on the ladies’ hat counter and I asked my mother what they were for. She explained that a black woman had to put a doily on her head before trying on a hat, because a white woman would not purchase a hat that had been on a black woman’s head.
