I lead a supremely conventional life in unconventional surroundings. Except for the time I passed a tiger roaming gracefully in the West 50s, free and untrammeled, perhaps an escaped guest from the David Letterman show; or the time, walking to work, I suddenly found myself surrounded by male and female models wearing — well, never mind. Aside from the odd encounter, I can easily slip into routine, which is how I like it. What interests me is a curator's lecture on a portrait in the American Wing of the Metropolitan Museum. Or the exhibit of Charles Dickens manuscripts in the Morgan Library. A quiet life.
