Let's say the GPS in one's car says the route takes the next turn to the left, but the spouse in the passenger seat insists it's in the opposite direction. Which way will you turn if faced with a snap decision?
That depends ...
(a) married men know (or, with progressive marital wisdom (tuition ?), eventually will come to know) the correct answer.
(b) single chaps probably will waste some time debating the pros and cons of the question and may even foolishly opt for the electronic option.
