"One thing about dealing with very rich people, particularly when they consider themselves philanthropists or industrialists or art collectors or have some other hobby that the rest of us can't afford: they expect other people to be interested in their lives. I understand that the Kings Louis of France, from number thirteen onward, used to have people come into their bedrooms in the morning and sit in a sort of gallery to watch them get up and go to the bathroom. It was considered a great honor to be invited, or you had to buy a ticket, I forget which. Maybe both."
