Kate Middleton became the Duchess of Wales when she married the first born of King Charles III and Princess Diana, the Prince William of Wales. Becoming a royal provides a lot of privilege and economic stability, but it also comes with a lot of responsibilities and protocols that you must follow.
As it turns out, Princess Kate of Wales is not totally contempt with the strict rules and she intentionally broke one of the most important ones, which has the King Charles III quite mad at her, and the rest of the royal family is just as well.
As weird as it seems, she broke a protocol by cordially greeting a group of people that were following her on a trip, and then she accepted taking pictures with a few of them.
This would be normal for a famous personality, just not for a Royal member, as they are supposed to be discrete, reserved and elite.
In the last few days, the wife of King Charles, Queen Consort Camilla Parker, was rumored to be angry at Kate Middleton for her attitude towards the rules that she was given when she entered the royal family members, and the pictures Kate took with some followers could be another reason for this drama.
Regardless, the public cannot find out about the drama between the two of them, so they need to cover up and act friendly on stage or when interacting. Luckily for us, there are a lot of people withing the royal family who are willing to leak this information to the public eye.
