It was reported today that the sat-nav system could break down within the next year. I hazard to guess that if it does, numerous marriages will follow. Outdoor Man and I get along famously until he wants directions in the car. He accuses me of being unable to read a map; I accuse him of not knowing his right from his left; he ignores my instructions then asks me to point; I hit his nose when doing so. Sounds familiar?

Certainly there are countless couples who will say that the lady hidden in the computer on the dashboard has saved their marriage. Even Outdoor Man never gets upset when she insists he makes U-turns that he has no intention of executing. Moreover, when she gets really irritated with him, he just turns her off; you can’t do that so easily with your wife!
