Dating is wasted on the young and the single
"Dating... is wasted on the young and the single. A young person in his 20s, unformed, skittish, goes out into the world and tries to fall in love, a project complicated by the bulky defenses that allow him to undertake so risky a venture in the first place. Now imagine that same person, many years into a stable marriage, anchored. He is no longer a stranger to himself; he is more likely to have forgiveness for human frailty. He can — theoretically — retreat to the safe harbor of his marriage at any time. What would it be like to be entranced by someone new, without needing, simultaneously to lay claim?"
