Later—around the time I was starting to see the last three or four months of our marriage in a clearer light, as a matter of fact—I began to understand that my decision to quit smoking when I did was perhaps not so unconsidered as it at first seemed, and a very long way from ill-considered. I’m not a brilliant man, not a brave one, either, but that decision might have been both. It’s certainly possible; sometimes we rise above ourselves. In any case, it gave my mind something concrete to pitch upon in the days after Diane left; it gave my misery a vocabulary it would not otherwise have had.
