Please,no discrimination

Ken had accidentally typed the wrong number on the phone. Instead of saying “Wrong number, Sorry.” to the lady on the end of the line, they started chatting!  They chatted for almost an hour! That’s when the lady on the other end, surprisingly asked him, “Are you a black American or white?” Ken being a black didn't say he was. Instead he told he was a white and started discriminating the black.  The lady listened tolerantly to him for 10 minutes. Then at last Ken asked her, “What ‘bout you? Are you a black or a white?”

“I…uh... I am a black.”
