The Royal Family are not like you and me. They live in houses so big that you can walk round all day and never need to meet your spouse. The Queen and Prince Philip have never shared a bedroom in their lives. They don't even have breakfast together.
Maybe it's true that we are all descended from the restless, the nervous, the criminals, the arguers and brawlers, but also the brave and independent and generous. If our ancestors had not been that, they would have stayed in their home plots in the other world and starved over the squeezed-out soil.
