My wife and I watched Larry King interview some of Ed Bradley’s colleagues last night. Leukemia took Bradley’s life yesterday and ended a notable career. All were professional colleagues with high admiration and a strong sense of connection to Bradley. But only one said he knew Ed both inside and outside the office. Bradley had kept his battle with leukemia a private matter, but Steve Kroft knew. I’m thinking Ed Bradley understood there is no particular limit on the number of friends you can have, but the really close friendships are a much smaller circle.
