The more I read, the more I am inclined to believe that David was the original role model for "Party Prince". Its what he did best.
You're right, Curryong, in remembering that Ziegler's biography has loads of the letters he wrote to Mrs. Dudley Ward and that they were constantly filled with bemoaning his state of affairs and how unhappy he was with them. There was a lot of moaning and groaning about just about everything. Its almost as if this person focused more on the negative things of life rather than the positives and was always wanting things to be different.
With reading the *huge* Shawcross biography of the Queen Mum now, during the first years of her marriage to Bertie, her letters are different and filled with how amazing she has found some things to be (such as going on safari) and I hadn't realized before that at that time, Elizabeth and Bertie were really quite fond of David and close with him and very often stepped out for the evening with him. Three really good friends. I haven't gotten up to the part about Wallis and the abdication yet but if what I've read so far is any indication, it will contain some really good insights into how it affected these three people personally.
