After some private details from the family life of the British royals were revealed from Prince Harry's memoir "Spare" (in German "Reserve"), Patti Davis, the daughter of former US President Ronald Reagan, has now published a guest article in the "New York times”.

The now 70-year-old once wrote an autobiography about her family, which she still regrets publishing, says Davis.

"I naively believed that if I shared my feelings, my own truth with the world, I could better understand my family," Davis said.

Over the years, however, she has learned that this is more complicated: "There is not just one, your own truth - the others who appear in our story also have their truths." Harry's brother William, Davis emphasizes, is sure his own version of things from the brothers' violent argument that Harry describes in his book.

"William is said to have told Harry to hit back after he hit him.

Harry refused - but in writing about the argument he has done just that."

"This will leave scars"

If she could offer her younger self any advice, Davis continued, she would say, "Shut up.

Not forever, but at least until you get a better grasp of the situation.

And to understand the long-term consequences of certain words.” As an example, she cites Prince Harry's decision to call his brother a “nemesis”.

"It will leave scars."

In addition, she has learned that "sharing every truth with the whole world" is not necessarily productive.

Famous families like hers and Prince Harry's would always be the focus and many would be interested in them.

“But not everything has to be communicated.

This is a truth that silence can teach one.

Harry seems to have followed the dictum that silence is not an option.

I would suggest, with all due respect, that it is.”

Her book was the fifth biography from the Reagan family

Davis had distanced herself from her family from an early age and lived a sometimes dissolute life.

She changed her last name and repeatedly took an explicit political stance against her parents and the Republican Party.

In 1992 she published the autobiography "The Way I See It", in which the then 39-year-old settled accounts with her family.

In it, she portrayed her mother, Nancy Reagan, as abusive, cold and cruel. She also stated that she was addicted to pills.

She characterized the former president as overly distant and criticized his political negligence.

At the time, Davis justified the decision to write the book by saying that the "misconceptions" about her family had encouraged "heartless interactions" with one another.

As early as 2004, the year her father died, Davis had expressed regret for having written "The Way I See It".

That same year, she released another memoir called The Long Goodbye, in which she recounts her father's Alzheimer's disease.

Reagan announced in 1994 that he had the disease.

As Davis describes in the book, the family found each other again through the father's illness.

"In the early stages of my father's Alzheimer's disease, when he was still having lucid moments, I apologized to him for writing an autobiography many years earlier, opening the gates to our difficult family life.

He was speaking less by then, but his eyes told me he understood," Davis said in a op-ed for The New York Times.
