Prince Charles and Princess Anne spent most of their childhood together, but it didn’t take their parents very long to realize that they had two different personalities.

When they were still very young, Princess Royal appeared to be boyish, while Prince Charles was reportedly a softy.

In 2002, Countess Mountbatten of Burma, a friend of the royals, said in the documentary “The Real Princess Anne,” that the mom of two was always full of life when she was much younger.

“She was what one calls a tomboy, really. Like all those types of children, she could be quite naughty – in a perfectly nice way – mischievous is perhaps a better word… In great contrast to her brother, who was much quieter. He enjoyed his penny too but not in the same way as Princess Anne,” she said.

At a young age, Prince Charles became aware of his future. He knew that he would one day become King so he had to exert the effort to be friendlier towards other people.

And when they got a bit older, Prince Charles and Princess Anne attended royal engagements together. Prince Charles got more of the attention of the royal fans because he is the future King. But it also didn’t take Princess Anne very long to get tired of playing second fiddle.

Meanwhile, a royal expert previously revealed that Prince Charles and Princess Anne were never close. In fact, they were never close to their younger siblings either.

On the podcast “Royals,” host Smita Mistry told royal commentator Angela Mollard that it seemed as though Queen Elizabeth II and Prince Philip had two different sets of children, and Mollard agreed.

“Those two are very different… Andrew and Edward, they sort of got on with it, they didn’t have the focus so much as younger children… They all get together and they’re all happy at family gatherings but there’s a lot of question marks over how much they see each other between times,” Mollard said.
