Years ago, I used to work with a black guy whose name was Dickie.On a somewhat related note, I've noticed that most black guys named Richard are called Richard, Rich or Richie -- never Dick. (Except for the comedian and activist Dick Gregory). Have you ever known a black Dick?
There was also Dick Allen, who played pro baseball in the 1960s and 70s. "Dick" had been his name all his life and he was supposed to have disliked being called "Richie" during his time with the Phillies.
