What he was thinking on this spring evening I have no idea, nor even what perception he had of himself as he straightened up in the gloom with the sledgehammer in his hands, but I am fairly sure that there was some feeling inside him that he understood the surrounding world quite well. He knew who all the neighbours on the estate were and what social status they held in relation to himself, and I imagine he knew quite a bit about what they preferred to keep to themselves, as he taught their children and also because he had a good eye for others' weaknesses.
