After reading several bios of Princess Margaret, I am wondering if she could have been diagnosed as bipolar. She certainly had her moments of volatility. Or maybe she inherited her dad's temperament. He had what they called his ``gnashes'' when he would lash out at people. There's a strain of that kind of volatility that has existed in the House of Windsor for multiple generations, after all.
I have learned a lot about King Gerorge VI of England (Prince Albert, Duke of York). I did not know he "would lash out at people".
Did he lash out at his sister Princess Mary?
