It's surprising how the past, whether old or recent, creeps up. Today I was, as usual, on the Common and, since the ground was very whet, walking on an old strip of concrete. I recalled that this had been placed there in the second world war, to provide for the landing and departure of airoplanes - a humbling thought!
I think this carefulness of thought continued on me when, at home, I was improving a decoration on the kitchen wall! In retrospect, I recalled that I had made each step with careful thought!
