“Having children has provided their adulthood with an instant and nonnegotiable sense of purpose and direction: they decide the length and location of that year’s vacation; they determine if there will be any leftover money, and if so, how it might be spent; they give shape to a day, a week, a year, a life. Children are a kind of cartography, and all one has to do is obey the map they present to you on the day they are born.”
