For the first eighteen years we were together, I’d give Hugh chocolates for Valentine’s Day, and he’d give me a carton of cigarettes. Both of us got exactly what we wanted, and it couldn’t have been easier. Then I quit smoking and decided that in place of cigarettes I needed, say, an eighteenth-century scientific model of the human throat. It was life-size, about four inches long, and, because it was old, handmade, and designed to be taken apart for study, it cost quite a bit of money. ‘When did Valentine’s Day turn into this?’ Hugh asked when I told him that he had to buy it for me.
