In Meghan Markle and Prince Harry's recent ITV documentary "Meghan & Harry: An African Journey," the British royal family members revealed quite a bit about their private lives. The type of transparency that the Duke and Duchess of Sussex offered to the public is reportedly something that Queen Elizabeth II has always struggled with in her 67-year reign.

According to Express, the monarch found it "very hard" to address the nation after Princess Diana's 1997 death due to finding it difficult to show emotion in public. As revisited by the publication, Penny Junor wrote about this very idea in her 2005 book, "The Firm."

"She was brought up, as people were in the Twenties, with a stiff upper lip; she was taught not to wear her heart on her sleeve, and to keep her emotions to herself," Junor wrote.

Continuing, she added, "It might appear that we are not as simpatico as we might be, but it's just that we don't show our feelings and that's the way it is. It doesn't mean we don't care." Additionally, she stated that she believed the difference could be due to "the generation gap."

This would not be the first time that age and societal shifts may have affected how the royal family made decisions on certain issues, as was evident back in August when the Queen was said to be moving with "the times" by breaking her own rule regarding Prime Minister Boris Johnson's trip to Balmoral.

Aside from the different opinions surrounding how open and vulnerable the members of the royal family should be with the public, there have also recently been other disagreements between members of the family on various issues as well, including reported disagreements between Prince William and Prince Harry regarding Archie Harrison's upbringing.
