 In 1960, when he was 15 years old, John Bibby stole a packet of biscuits from his boss. This crime happened while John worked in a shop in a town in the north of England. John took the biscuits from the shop manager Les Simpson while Les was not looking, and then he ate the whole packet. Fifty years later, John managed to find out where Les lived. John drove to Les\'s house and gave him a packet of biscuits to replace the one he had stolen fifty years earlier. All that time, John felt guilty about what he had done, but in fact Les was not even aware of the theft.
