My son sat in the backseat of the car on the way to soccer practice. He was fiddling with my iPod.
"Dad, how do you get rid of this?" he asked.
I'm a stickler for details, and I needed more information. I said, "What are you trying to get rid of?"
He fiddled for a second and then said, "Nothing."
"Oh, that's easy," I said. "Anything."
"You want to get rid of nothing. You can use anything to get rid of nothing." Problem solved.
