We'll be keeping an eye on what's going on in the marriage of the Prince and Princess of Wales. William and Kate seem to be more in love and in touch than ever in their 12 years as a couple. According to the Daily Express, there is a "mischievous side" to their relationship that has created a "strong bond."

This week alone, Kate gave William at Prince Charles' Scottish coronation the "butt pom-pom" (I'm obsessed with that phrase) that is now becoming her signature, and the same week she packed on the PDA with a kiss at a polo match. Body language expert Darren Stanton said of their public interactions, "They have a very mischievous side to them.

Their relationship, which has lasted nearly 20 years, "has clearly gone from strength to strength, and they clearly have a very deep trust and deep relationship," Stanton said. And as for PDA, he said of two people as unconventional as Prince Harry and Meghan Markle, "you rarely see expressions of affection by members of the royal family, especially the late Queen Elizabeth and King Charles." This proves that William is not afraid to show his love and deep rapport with Kate." Of William, Stanton said he "seems quite genuine and authentic" and that it will be "interesting to continue to see how he grows further as he moves toward the throne." Kate is said to be a big part of William's personal growth, Stanton said on behalf of Betfair Casino.

"I think Kate has played a big part in his development. 'When they met, they weren't the most confident people. As for Kate, she played a huge role in his development as a person, as a future monarch, and with regard to his level of confidence in the world. She also grew a great deal over the years, even more than William. Initially introverted and reluctant to get involved, she has become an integral part of the Royal Family. The two are now considered the highest-ranking members of the active royal family. I am convinced that Kate's increased confidence has made William feel more secure as well."

In polo in particular, Stanton said Kate's support showed "their strength as a couple," according to the Daily Express.

"We couldn't be closer. Kate's hand is in the exact same position as William's, and watching them together you can tell how happy they are." Kate's smile when William kisses her on the cheek was complete passion from her side. He makes her light up. The way their arms are folded also speaks volumes about their relationship. Not everyone hugs or holds you like that. Hugs like that come from someone who knows you inside and out."

Micah Meyer, a royal etiquette expert, told "People" that there are no formal rules for PDAs in the royal family, and their use is left to the discretion of each couple. (For example, Queen Elizabeth and Prince Philip use one, Prince Harry and Meghan Markle use the other.) ) "Senior members of the royal family will not be told how to interact, when they can and cannot show PDA. 'The royal family often tailors their PDA to the prestige of the event they are attending. Sober or more formal events are deemed more appropriate for PDAs than more casual events, and PDAs are less likely to be seen. "

Meyer, founder and director of Beaumont Etiquette, said of the royal PDA, "A hand behind the back or holding hands is a safety measure, as it shows care and comfort." The occasional peck of sweet Sussex is one thing; lewd snogging is another."
