This was the way I'd always thought about Prince Charles:-

When Prince Charles hit bottom after his separation from Diana, in 1992, he unburdened himself about the miseries of his youth to Jonathan Dimbleby, who was writing an authorized biography. Dimbleby noted that, as a little boy, Charles was “easily cowed by the forceful personality of his father,” whose rebukes for “a deficiency in behaviour or attitude . . . easily drew tears.” While brusque, Philip was “well-meaning but unimaginative.” Friends who spoke with Charles’s permission described the duke’s “belittling” and even “bullying” his son. Charles was less harsh about his mother, but his opinion had a bitter edge. She was “not indifferent so much as detached.”
His father transferred him to Cheam School, in Hampshire, where Philip himself had been sent at the age of eight. Charles was just shy of his ninth birthday but considerably more vulnerable than his father. He suffered from acute homesickness, clutching his teddy bear and weeping frequently in private. “I’ve always preferred my own company or just a one to one,” he has said. As heir to the throne, he made an inviting target for school-mates, who ridiculed his protruding ears and called the pudgy prince “fatty.”
Later he went to Gordonstoun:

Charles did not feel a good fit at Gordonstoun and later labelled it as “a prison sentence”, calling the school “Colditz in kilts”. To top it off, according to fellow school friends, Charles was relentlessly bullied.
Charles wrote in a letter home in 1963 describing the tough time he was having, it read: “The people in my dormitory are foul. Goodness, they are horrid. “I don’t know how anybody could be so foul.” In another, he wrote: “I hardly get any sleep in the House because I snore and I get hit on the head all the time. It’s absolute hell.”
I feel that any kid who gets sent away aged 8 and writes plaintive letters back home which are basically ignored would have some trust issues with his parents.
