In his memoir “Spare,” he described his last interaction with her over the phone.

So I’d been short with her.

I wished I’d apologized for it," he said (viaPage Six).

“I don’t think any child should be asked to do that, under any circumstances.”

In his memoir, Prince Harry broke down in tears once Princess Diana was finally buried.

“I remember just feeling completely numb, disorientated, dizzy,” he said (viaABC).

“You feel very, very confused.

And you keep asking yourself, ‘Why me?’

All the time, ‘Why?

What have I done?

Why has this happened to us?'”

In the end, he took a slightly different approach to grief than his brother.

Where Prince Harry shut down his feelings, Prince William compartmentalized.

“I wouldn’t let it break me.

I wanted it to make me.

If I can be even a fraction of what she was, I’ll be proud.”

Anderson wrote: “I don’t think people realize how really stricken he was by her death.”

And then what happens?

On the phone and in public, King Charles became all business.

Prince Harry recalled his father’s somewhat distant attitude at the time “Pa didn’t hug me.

He wasn’t great at showing emotions under normal circumstances” (per “Spare” viaCBS).

A letter written by Queen Elizabeth at the time also corroborates this sentiment.

“William and Harry have been so brave and I am very proud of them.”

“She was an exceptional and gifted human being.”

They have lost their mother!'"

Princess Anne waves to reporters

(viaTown & Country).

She told theDaily Mail: “I personally read around half a dozen of the letters from Prince Philip.

Diana let me see them.

And although they were tough, it was clear to me he was trying to be constructive.

… Philip felt Diana and Charles did not have to be divorced.

They could live separate lives, with separate apartments, if necessary, but they could remain together.”

When she died, everyone got as hysterical as she was.’

She worries that she failed Diana, who could have used a strong woman to support her."

Princess Anne felt the royal family’s choice to grieve privately at Balmoral was for the best.

I don’t think either of those two [children] could have really been able to cope."

She also acknowledged how difficult it was for the boys to adjust to the devastating loss of their mother.
