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 backseat driver in the world. I have long thought this, though she would deny it.
She claims she seldom, if ever, makes comments about my driving. I, of course, claim the opposite. And now I have proof!
The other day, we were headed to the mall and my daughter piped up, "Daddy, before you married Mommy, who told you how to drive?"
