It must have been so much fun being one of Cookie's guests. She certainly knew how to enjoy herself and everyone, be them detractor or idol worshipper says/said what a good sport she was socially.
The dynamics of her relationship with the present Queen must have been fascinating. I mean being such a sybaritic (my favourite word at the moment to describe all thing Cookie related) Cookie must have raised her eye brows at what she had produced when Lilibet went around turning lights after her etc!(If I hasten to point out, that that anecdote be true!!!)
Few of us alas shall be alive to drool over their private papers....ho hum! Just think what goodies biographers of the future shall unearth from Cookie's papers in the RA!
