I'm no fan of Charles and the sooner my country becomes a republic the better (although I had a soft spot for the Queen and love Anne) however let's not forget:
His mum has just died.
She was barely cold when he was made king.
He's already being compared to his mum with people saying he won't be as popular as she was, well of course not because she had 70 years on the throne and all that time to cultivate the image she wanted to show to the world. Charles is going to have to do the same but in a much much smaller time frame. They're also two different people. Hardly fair to compare.
He has a brother who is a sex offender (not his responsibility obviously but there would be people who judge the entire family).
His two sons barely speak to one another.
His mum's coffin with her dead body inside is being driven around for the entire world to see, yes I know it's tradition but there's something a little off about it. And if the coffin is empty then that's also disturbing.
At the end of the day no matter how royal and privileged he is he's still a human and humans have emotions and how we deal with those emotions depends on a few factors mainly; the environment you've grown up in, your personality, how much resilience you have (which can only be gained by life experiences) and many other factors. I think he should be cut some slack and I say that as someone who is no fan of his! Whether he continues to behave like this only time will tell.
