My History and Economics master at school, who was also a close neighbour, had been a Squadron Leader during WW11. He left teaching to become an M.P., Home Secretary and finally a Baron. He had a police post built on the rear of his garage and, much to the concern of his police guard, could be seen most Sunday mornings cutting his front lawn wearing his old wartime KD shorts and a T-shirt. He was known to all and sundry by his first name. No frills there.
