About five years ago the battery in my beat-up VW beetle had died because I left the lights on overnight . I was in a hurry to get to work on time so I ran into the house to get my wife to give me a hand to start the car.

I told her to get into our second car, a prehistoric oversized gas guzzler, and use it to push my car fast enough to start it. I pointed out to her that because the VW had an automatic transmission, it needed to be pushed at least 30 MPH for it to start. She said fine, hoped into her car and drove off.

I sat there fuming wondering what can she be doing. A minute passed by and when I saw her in the rearview mirror coming at me at about 40 MPH, I realized that I should have been a bit more clear with my directions.
