They are here for the awarding of the ‘upper class twit of the year award’
I think Camilla looks lovely, age appropriate, supposedly has a great sense of humor (she needs it as a member of the royal family) and I think she handles Charles well and keeps him happy and content. She has earned her keep; it was Diana who was the unstable, emotionally unhappy and stunted woman that made Charles miserable.
He really tried with her but she was nuts. A delicate cutter who was a food binger (liked to throw it up after eating it). By the way, in psychological terms, a delicate cutter is one who likes to cut their arms up with delicate cuts, because they consider the pain from the cuts to somehow be preferable to the pain in their emotional lives. Diana was one sick puppy, a pretty one, but a sicko.
