I got in a cab last night heading from Washington D.C. to the Dulles airport. I was a block from the White House and traffic was stopped behind a crowd that was pushing its way in to see the president.

The old Ethiopian cab driver suddenly kicked the taxi into gear and zipped around a line of cars, edging us five cars closer to freedom.

"I hate traffic", he grumbled.

"You picked the wrong job, then, didn’t you?"

"No! I love my job. My job is to fight the traffic."
