Reliable Source: Hey, isn't that. . .?: Timothy Geithner

Tim Geithner in a random act of kindness Friday night. The former Treasury Secretary, who just joined private equity firm Warburg Pincus as managing director, was walking by himself in Georgetown when a homeless man asked for a dollar. Geithner took out a buck, handed it to the man and said, "Good luck to you." How often, a bystander asked us, do you see the guy who signed the money giving it away?
