I found this interesting article on the Daily Mail website about the Queen Mother:
http://www.dailymail.co.uk/femail/article-1214573/The-Queen-Mother-That-spiteful-old-soak-dedicated-making-lives-hell.html
Whether or not you believe what the article says is up to you. However, it does make some very interesting points about social attitudes of the aristocracy and royalty and the pressures they were under, especially in the past.
It also shows that even when you are rich, you may not have to worry about enough food or money, but you are subject to different pressures:
1) You may in love with someone other than your husband
2) You may have family members with disabilities who you deny exist (to us now, this may seem cruel and very un-PC but in the past, this was what happened)
3) A family member marries beneath them and you ignore and shun them
4) Behind closed doors you have a violent temper, and are argumentative and mean. You also have an addiction to alcohol or other substances. In public you are gracious and thoughtful and appear generous and kind.
All this is great material for a novel!!
