About ten years ago, there was a Princess Diana exhibit that travelled to various museums. It was put together by her brother. It exuded his love for her. There was a lot about Diana's good intentions and her passion for her various charities.
After seeing that exhibit, I can't criticize her. She was in a position that didn't suit her. She behaved in a way that showed a lack of maturity or commitment to the role she accepted.
If she had become Donald Trump’s trophy wife (I think he was interested in her at one time), she would now be our First Lady and hosting the British royals here or going on state visits to Old Blighty.
