a father for whom everything is an unshakable duty, for whom there is a right way and a wrong way and nothing in between, a father whose compound of ambitions, biases, and beliefs is so unruffled by careful thinking that he isn’t as easy to escape from as he seems. Limited men with limitless energy; men quick to be friendly and quick to be fed up; men for whom the most serious thing in life is to keep going despite everything. And we were their sons. It was our job to love them.
