According to murmurs from King Charles' aides, the king is known for throwing "child-like" tantrums and is prone to occasional outbursts. The silver lining, however, is that his majesty tends to get unruly over minor things, and heads of state can swiftly bring him back to calm.
From OK! Magazine:
"They know he can get very cross about quite minor things, and they have yet to find out how he will react in certain situations," royal author Robert Hardman wrote in his new book, The Making of a King: King Charles III and the Modern Monarchy. "At the same time, they know that Queen Camilla is a strong voice of common sense in that regard."
"That's one of the reasons why Queen Camilla is so marvelous," one of His Majesty's longtime friends, Lord Chartres, shared with Hardman. "She can be robust in her views, and that allows him to relax. When things go wrong, and you have to keep being nice, you need an intimate who can talk you down."
On the flip side of those details, royal scribe Christopher Andersen shared with an outlet how the King can be "very moody, very temperamental. He has a volcanic temper, in fact. He’s very capable of flying into rages." The author wrote how "after accidentally dropping a cuff link down a drain, Charles once pulled the sink off the wall to which it had been mounted, then grabbed his valet by the throat in his fury."
Furthermore, the then-Prince of Wales reportedly threw furniture all over the place during some of his "vicious" back-and-forth arguments with the equally temperamental Diana, Princess of Wales, in the 1980s and '90s.
