For Kate Middleton and Prince William, PDA is just not a high priority! Throughout their more than six years of marriage, the Duke and Duchess of Cambridge have often refrained from touching or even holding hands in photos — leading many to wonder why they act so stoically around each other.

According to a royal etiquette expert, Kate and William’s lack of PDA is nothing personal — they’re just being professional! “There is no actual etiquette or royal protocol that says the couple must refrain from PDA. The likely reasoning is more that while traveling on a tour such as the India trip, technically the couple are working representatives of the British Monarchy. The couple are likely to show very little PDA, if any, to remain professional during their designated roles abroad,” Myka Meier recently explained to [People](,,2039522221000950,00.html)_.

“Going to somewhere like the [Taj Mahal] is very much an official, straight-laced kind of event and you wouldn’t hold hands there if they’re there on an official visit,” longtime royals writer Judy Wade added. “But I noticed they did let their hair down at the sporty occasions on the tour, and there was a great deal of fun, and [William] kept putting his arms around [Kate]. Different types of occasions call for different types of behavior.”

Though William and Kate choose to act uber professional during their official outings, Prince Harry and his girlfriend, Meghan Markle, weren’t worried about showing a little PDA at the 2017 Invictus Games. On Monday, Sept. 25, the duo — who have been dating for just more than a year — were spotted canoodling courtside at a wheelchair tennis event and even photographed adorably holding hands! Maybe William and Kate can take a page out of Harry and Meghan’s royal romance book and give fans a bit more PDA in the future!
