Public Displays of Affection

Until Diana came along, the royal family had always been very proper in public. There was no holding hands, no kissing, and no hugging - so Diana's tactile nature tore up the rulebook on protocol, and her sons appreciate that still now. In 2017, Harry recalled in a documentary to mark the 20th anniversary of Diana's passing, "She would just engulf you and squeeze you as tight as possible. And being as short as I was then, there was no escape, you were there and you were there for as long as she wanted to hold you. Even talking about it now I can feel the hugs that she used to give us."

While Harry has been known to offer hugs as he's greeting young fans, William is always on hand for a kiss and a cuddle with his children.
