Charles is apparently meant to work very hard. He is reported to work well into the evening or night most days. Reading briefings, doing research, preparation etc. It's not just the hand shakes etc, it's the prep beforehand. Making sure you know exactly what a charity is doing, who works there, who to speak to etc. I know they have aides, but they need to be totally on top of their game at all times, look interested and engaged, be switched on every minute. That is exhausting. Even if they do have drivers and lackeys. One of the things I really noticed was Meghan Markle mentioning how totally exhausting this is . I get the feeling she wasn't prepared at all for the sheer physical and mental exhaustion that sort of 'work' generates. There is absolutely no room for an off day, feeling out of sorts, or having a memory lapse. Add to that the fact that there are hundreds of cameras trained on you every second virtually, catching every expression , which will then be analysed , criticised and reported on across the world. For women, there is the emphasis on clothes. Too expensive, too drab, too revealing, they look fat... on and on and on.
Every Xmas there is an expectation that they will attend church, be wheeled out for public display and the day is spent at a stuffy function which hasn't changed in over a hundred years. Children are in the nursery, and the whole thing is choreographed to a tee. No fun in pyjamas or opportunity to spend the day somewhere else Kate managed it for the odd year, but now is expected to be at Sandringham every time. August is spent at Balmoral, come what may.
No amount of houses, castles, clothes or staff could compensate for that as far as most people are concerned. This why Harry struggled to find a wife for years. Who would want to spend their life as public property? They are performing martinets. That takes its toll.
Obviously I am talking about working Royals. For people like Zara or the York sisters, it is a whole different ball game, as they get the perks without the stress and scrutiny on the whole. This is why I imagine Charles wants to slim down the monarchy, quite rightly.
