A Harry Marsh was
a driving examiner who had to rest people who wanted to get a driving-licence.
One day he came out of his office as usual and saw a car beside the driver and
told him to check the lights, then the brakes and then all the other usual
things. The driver performed everything promptly and faultlessly, without
saying a word.
Then Harry told the driver to start his engine and drive forward, Then he
told him to turn right into a side road, stop, go backwards into another side
road and then drive to the office again .
One the way, the driver said to Harry
politely, ‘could you please tell me why we are doing all these things ? I was
passing through this town and only stopped to look at my map.’.
