It’s been 23 years since Princess Diana was killed in a car crash at the age of 36, and while her youngest son Prince Harry is now 36 himself, a body language expert is claiming that he is still a “young boy mourning his mother” in many ways.

Body language expert Judi James spoke to the U.K. Express about the emotional message that Harry and his wife Meghan Markle wrote on their Archewell website on New Year’s Eve. The statement read:

“I am my mother’s son. And I am our son’s mother. Together we bring you Archewell. We believe in the best of humanity. Because we have seen the best of humanity. We have experienced compassion and kindness, From our mothers and strangers alike.

In the face of fear, struggle and pain, It can be easy to lose sight of this. Together, we can choose courage, healing, and connection. Together, we can choose to put compassion in action. We invite you to join us. As we work to build a better world, One act of compassion at a time.”

James believes that the statement speaks volumes as to the heartbreak Harry still feels over his mother’s death in 1997.

“First there is the suggestion that Harry is the heir of Diana’s passion for compassion,” she said. “He is presumably telling us in capsule form that he is the chip off the block, that what we saw in his mother’s behavior and actions we should expect from him because he is motivated by the same values. It also sounds like a bid to inherit her popularity and the love people around the world had for her.”

James went on to say that Harry’s new life in California has allowed him to relate to the “isolation” Diana felt from the Royal Family following her divorce from Prince Charles.

“But this open declaration could also be read in other ways,” the expert said. “Harry is the child of a very painful, divisive divorce and before Diana died there was a clear rift between her supporters and the crown. Harry’s loyalty sounds obvious here, and it seems telling that these words are pinned up in a form of high-emphasis isolation, making it sound as though he is picking up his mother’s banner from his power-base abroad.”

James concluded by saying that the language Harry used in the statement shows how devastated he still is over his mother’s death.

“Harry specifically picks out his mother as being the one showing him compassion and kindness,” she said. “The use of the words ‘we have experienced…’ at the start of that phrase sounds telling. Harry seems to be referring to the kindness and compassion Diana showed to him as well as to the world, or he might have used the word ‘witnessed’ instead.’

“There is a sense in these words that we are still looking at the young boy mourning his mother and the ‘kindness and compassion’ she gave him,” James finished. “The couple even refer to ‘fear, struggle and pain’ as though defining their own personal experiences.”
