My wife cannot ride in a car without telling whoever is driving what to do, when to do it, etc. She is, bar none, the worst back seat driver in the world. I have long thought this, though she would deny it. She claimed she seldom, if ever made comments about my driving. I, of course, claimed the opposite.
Now I have proof. The other day we were headed for the mall and my daughter piped up, "Daddy, before you married Mommy, who told you how to drive?"
