my father was driving to work early one morning.After he had been driving for a while he noticed a cop on a motorbike following him but didn't take much notice.After about ten minutes , the cop pulled up at a set of traffic lights ; as my father rolled down his window to ask the cop what the hell he wanted he noticed his indicator light was flashing and realised it must have been left on since he left home.
"When do you intend turning left " the policeman asked him sarcastically to which my dad ,who prided himself on the speed of his tongue, replied as quick as a flash " O, at Tower Bridge "(which was about fifteen miles away)
But the cop had the last laugh "Well, he said, you're certainly giving sufficient notice" and drove off leaving my old man fuming.
