Would be watched all the time by the press, others and sometimes your own family. Have no privacy. I broke my wrist four months ago and if I were a royal this would be headline news. If someone had film footage of me falling and breaking my wrist (which occurred in a public place), it would be on CNN, You Tube, etc.
Royals visit various people, places, and things. I would imagine some of people they visit, or the places they go to are boring to them. Perhaps they have no interest in the particular people or places they visited. Of course they could never say this and would have to pretend that they have interest in whatever or whomever they are visiting. I would want to pick and choose these things, something a royal can't really do.
Don't always think before I open my mouth. If I have an opinion of something, I will usually tell you if you ask. In a store I loudly said that women in one social club were snobs. People heard me, including a member of this club. If I were a royal, the headline would say, "Royal blasts social club, says only snobs need apply."
A royal doesn't really have the freedom to come and go as they pleased especially if they are the heir to the throne or the monarch. Imagine if a heir to the throne or a monarch wanted to go to a regular movie theatre or wanted to take a walk in a public park in the country where they lived. Forget about the walk in the public park and if they went to a movie theatre it would have to be on a night when few people are there. Otherwise they would be hounded, people would be trying to get a picture of them, etc
I am who I am and I don't pretend to be someone I'm not. Some royals try to mold themselves or they are forced to mold themselves into people that they really aren't. Eventually the truth comes out or people figured it out. You can't hid your truth self forever.
A friend told me that if I were a royal, I would have been admonished many times for things that I said. A royal isn't supposed to be strongly opinioned and is supposed to be bland as far as that goes.
I would probably be sent to a princess school or some type of school to learn how to behave like a priness. She also said they probably would lock me up somewhere, never to be seen in public again or heard from again. She was joking about this (being locked up somewhere) but I wonder.
