Poor old Charles he was such a shy lad. Given his position in society I get the impression he would have been far happier just being a gardener and a private person. He has made some dreadful choices but it's good he does now seem very happy with Camilla.
It's a pity that the stuffiness of the Royals when he was in his 20s possibly prevented him from the path he would have liked, but he should never have led Diana Spencer on and married her. He was the one with the power, she was too young and too naive to get what he was about.
It probably did not help her confidence and self esteem that she appeared to have been the butt of family jokes, they referred to her as "Brian" the rather dim snail in the Magic roundabout.
But how many of us have done things we now regret.
