When I was a kid we were visiting friends with my Mom and Dad, and I'd had enough. I said I wanted to go, and they told me if I wanted to, to go drive myself home. I got in the car, got the key off the visor and got it started. Dad got there very about 3 seconds after I hit the starter and put a halt to my trip. I might have been 5, but I knew the way home and how to work a clutch.
Kids don't get sarcasm.
