THE DIFFERENCE BETWEEN LUCY’S affair with me, and my affair with someone I was sure I’d never love, is that Lucy thought I was a ladder to a new life. I thought I was having a smutty daydream. It is Lucy’s vision that sounds like fantasy—like midlife crisis, when you consider that she was in her forties, and I was in my twenties, and that we fell in love the first night we met. But it was my vision of infidelity that turned out to be delusional.
