“In the year 2000, it was standard practice for the successful chief executive officer of a corporation to shuck his wife of two to three decades’ standing for the simple reason that her subcutaneous packing was deteriorating, her shoulders and upper back were thickening like a shot-putter’s—in short, she was no longer sexy. Once he set up the old wife in a needlepoint shop where she could sell yarn to her friends, he was free to take on a new wife, a “trophy wife,” preferably a woman in her twenties, and preferably blond, as in an expression from that time, a “lemon tart.” What was the downside? Was the new couple considered radioactive socially? Did people talk sotto voce, behind the hand, when the tainted pair came by? Not for a moment. All that happened was that everybody got on the cell phone or the Internet and rang up or E-mailed one another to find out the spelling of the new wife’s first name, because it was always some name like Serena and nobody was sure how to spell it.”
