You Gonna Wreck It?

As teenagers, my Dad was very generous with loaning out his vehicle. He would just say one thing, to which you HAD to respond correctly, or just forget the car thing! The question was always, "You gonna wreck it?" The answer was of course, "No sir!". Dad would then hand over the keys and say. "Well then, OK." I certainly was NOT going to wreck the car. That would just be wrong!
It was a good trick on Dad's part. It kept the thought in my mind to be careful because wrecking the car was Not an option.
