The ‘Naughty’ Thing Princess Diana Used to Send to School With Prince William

Prince William, the Duke of Cambridge, used to receive very “naughty” cards from his mother, the late Princess Diana, he revealed in the documentary, Diana, Our Mother: Her Life and Legacy. 

Prince William revealed he’d receive ‘embarrassing, very funny’ cards from Princess Diana.

“She had a very cheeky sense of humor,” Prince William, second in the line of succession to the throne, said in the documentary. 

“She was a massive card writer and she loved the rudest cards you could imagine,” he added before sharing a fun memory of his mother.

“I would be at school and I’d get a card from my mother. Usually, she found something you know, very embarrassing, very funny card, and then sort of written very nice stuff inside. But I didn’t open it in case teachers or anyone else in the class had seen it.” 

“She was very informal and really enjoyed the laughter and the fun,” Prince William added. 

Princess Diana’s motto on being ‘naughty’ 

Prince William’s younger brother, Prince Harry, the Duke of Sussex, explained in the documentary their mother had a saying about mischief. 

“Behind closed doors, she was a loving mother and an incredibly funny person,” Prince Harry remembered of his late mother.

“One of her mottos to me was, ‘You can be as naughty as you want, just don’t get caught,’” he recalled.

Clearly, she followed the same motto she preached to her young sons. “She was a total kid through and through,” Prince Harry said. 

Prince William buried himself in schoolwork after Princess Diana’s death

Sadly, Prince William would no longer receive funny cards in the mail from his mother after she died in 1997 when he was only 15 years old. 

Royal expert and biographer, Katie Nicholl, wrote in her book, Kate: The Future Queen, that after his mother’s death, Prince William used school as a distraction

Before, Prince William hadn’t been the best student at Eton College, but after Princess Diana died, he studied much more, and his grades reflected it.

“He had pleasantly surprised his teachers at Eton when he passed each of his twelve GCSEs, excelling in English, history, and languages,” Nicholl wrote in her book. 

A student who passes their GCSEs, or General Certificate of Secondary Education, means they can move on to university. 

“The loss to Prince William and Prince Harry was almost unbearable, and when William returned to school, he threw himself into his studies as a distraction,” Nicholl said.

He thinks of Princess Diana often

Also in the documentary, Prince William revealed as an adult, he thinks of his mother often. 

“There’s not many days that go by that I don’t think of her,” he said. “I have a smile every now and again when someone says something, and I think that’s exactly what she would have said, or she would have enjoyed that comment. So they always live with you people, you know, you lose like that.”

Prince William also said he keeps his mother’s memory alive for his children by telling them stories about their late grandmother at bedtime. Needless to say, although Princess Diana is gone she will never be forgotten.
