My Dad, having immaculately performed a very responsible job for many years, retired on his 65 birthday, with a very smalll pension and promptly proceeded to 'act daft, go half fare' very successfully for the rest of his life. He adopted a slightly bemused manner and expression and wandered backstage, into VIP lounges, other people's social events, business receptions etc. partaking of the purvey and free drinks, played golf on many of the top courses, entering through the member's gate or simply starting at the 2nd hole, abroad on holiday he would join other people's tours and slip quietly into the best hotels, often enjoying lunch or dinner there. He was never challenged or flung out because he looked the part - very distinguished, tall and tanned, wearing his good suits and casual clothes picked up for peanuts at jumble sales in posh towns. In this way he became a familiar face and indeed a friend of many of the top golfers, politicians and folk singers of the day.
He was the man who had his shopping packed for him and carried to his car, who would arrive in his old banger but be photographed beside a Merc., who wore a posh club tie which no one could quite identify , who 'couldn't' find his seat and was upgraded to first class. He enjoyed his retirement to the full, his justification being that his Father, FIL and some good friends had died in harness and it was his DUTY to make the most of retirement.
I lack the self confidence to 'boldly go' as he did but admire his spirit.
