But William had other plans and they did not include Harry.

“I couldn’t make sense of it.

I was like, ‘What do you mean?

We’re now at the same school.

And I took that personally.”

“I tried it on.

Willy and Kate started roaring with laughter,” Harry wrote.

The backlash was instant: “A senior royal dressing up as a Nazi for a laugh?

All that time together in Lesotho, he’d never mentioned it,” Harry wrote.

“We’d never again ride together across the Lesotho countryside with capes blowing behind us.

The queen agreed, even though fiances had never been allowed at the celebrations previously.

And maybe they never really did.”

Still, it was hard to believe that they couldn’t pop in even once.
