“I don’t think she was a commoner”
No she was Lady Diana Spencer, daughter to the Earl of Spencer. Her bloodlines were bluer than Charles.
I think she was naive, spoiled, and pretty much an airhead. Charles is a tool but I’m sure she bored him to tears. If she had been middle class in the US she’d have probably been talked into giving BJ’s to the football team behind the bleachers when she was 15. I don’t find much to admire in any of them. The only ones worth anything died over the last couple of years. The ones now are just well dressed trailer trash.
