The boys love to go out. Michael often follows me round the house clutching his shoes and looking at me hopefully.
The boys have one pair of shoes each and one pair of sandals each. The weather has turned nasty and we have discovered that one of the shoes has disappeared. In rotation, our unfortunate sons have been guilty of the fashion solecism of wearing sandals with socks. Also, more worrying, they have taken my keys and hidden them. I foresee vast expenditure.
When my father was a student in the 1940s, he had a friend who was a physics student. His friend said to him one day “I can’t wait for the Summer when I can get out of shoes again.” There is something about the juxtaposition of not wearing shoes and physics that appeals to me.
