Prince William and Prince Harry reportedly inherited one habit from Prince Charles, which they do when they are not feeling very confident.

Darren Stanton, a body language expert, analyzed Prince Harry’s gestures while at the One Planet premiere at the National History Museum in London earlier this month. While speaking with Express, Stanton said that it was evident that the Duke of Sussex was playing with his ring finger.

“Some could argue that he appears to be playing with his ring finger, which again is a gesture both William and Harry have inherited from Charles to signify they are feeling unconfident,” he said.

Prince Harry wears a ring band so it’s easy to spot him playing with it while out in public. However, Prince William and Prince Charles have both opted to not wear rings. Even if this was the case, the two male royals still wring their hands in front of them during instances wherein they are feeling uncomfortable.

Body language expert Judi James said that playing with the ring could only mean that husbands are missing their wives.

“In Harry’s case, this looks like a self-confident ritual performed for two reasons, when he’s feeling under pressure or lonely. Firstly, it allows him to create a language barrier with his arms but by seeking out his wedding ring to touch and play with it suggests he’s missing the backup and support of his wife here,” she explained.

But according to James, the self-confident ritual would take on an entirely different meaning if Prince Harry or anyone who is wearing the ring would pull it up and down the finger or even take it on and off. Doing so could signal a rift or a potential divorce.

Prince Harry and Markle have been married for less than a year, and they have always been touchy-feely towards each other. The couple will celebrate their first wedding anniversary on May 19.
