Learning from Politicians
When the Clinton administration left the Old Executive Office Building, staff members removed the "W" key from many of the keyboards. In contrast the Bush ("43") administration set a new standard for exiting with grace. Message: Leave with class.
Bill Clinton and "Bush 41" set aside their differences enough to travel raising funds to help people devastated by a hurricane. In the process they reportedly became good friends. Message: You don't have to agree to get along.
When Joe Biden joked about how Supreme Court Chief Justice Roberts muffed the swearing-in lines, Barak Obama, demonstrating his unwillingness to be petty, reached over and stopped his vice president with a gentle touch. Message: Reprimands don't always have to be verbal.
(Update January 28: Biden apologizes to Roberts)
