Oh for goodness sake, the RF, in many ways, are no different from any other families. They fight, they argue, some resent their siblings, some parents play favourites.
The differences are the RF “rows and scandals” are played out publicly.
The book and the Oprah interview were big mistakes, however many books exist about many royals, some with the royal approval and cooperation, some not.
Andrew, the King and Diana, Princess of Wales all gave disastrous public interviews and all had staff and sometimes friends, who deliberately or accidentally released snippets to the press or others.
I don’t take sides, I don’t know any of them personally and I simply have little interest other than hoping (most of them) remain in good health and can resolve their differences.
On a personal level, imo, King Charles would like to see his Californian grandchildren and reunite with his younger son.
