Princess Anne has spent decades earning a reputation for being one of the most direct and no-nonsense members of the Royal Family, but even that famous toughness appears to have caught Princess Diana’s younger brother completely off guard when he was just 17 years old.

In his new memoir, Swan Song: Diana, My Sister, Earl Spencer looks back at the extraordinary days surrounding the wedding of Prince Charles and Lady Diana Spencer, including one formal dinner at Buckingham Palace that left him feeling rather painfully out of his depth.

Charles Spencer revealed that the dinner took place about 48 hours before Charles and Diana were due to marry. That implies that the atmosphere inside the palace was already filled with anticipation and excitement. Yet for the teenage Earl, the evening quickly became an exercise in navigating royal etiquette, particularly after he discovered exactly where he had been seated.

Spencer knew he would be at Princess Anne’s table, but then came the realization that he would actually be sitting beside her.

That, as it turned out, was enough to make him nervous.

Earl Spencer Thought He Had Found The Perfect Conversation

Trying to make polite conversation with his royal in-laws, Spencer decided to mention something he assumed would be an easy and pleasant subject: Princess Anne’s daughter Zara’s christening, which had taken place that very day.

He recalled turning to Anne and asking, “And how did your daughter’s christening go today, Ma’am?”

For a nervous teenager sitting beside a senior royal, it probably seemed like a perfectly reasonable question, particularly because Spencer expected Anne to welcome the opportunity to talk about her baby daughter’s special day.

Instead, he received a response that completely threw him.

According to Spencer’s recollection, Anne stopped, looked at him “witheringly,” and simply asked: “Tell me, how’s a christening supposed to go?”

It was apparently the last thing the young Earl expected to hear.

Spencer admits that he immediately found himself without an answer, writing that he “blushed bright red” and had no reply to Anne’s question.

The exchange may have lasted only moments, but the impression it left on him clearly endured.

The Awkward Moment Became A Lesson In Royal Conversation

What makes the story particularly memorable is the way Spencer contrasts his encounter with Anne against another conversation taking place elsewhere at the same dinner.

His brother-in-law Neil, he recalled, was making what Spencer described as “easy conversation” with the Crown Princess of Japan, discussing something as ordinary as rice cultivation.

For the teenage Spencer, the contrast could hardly have been greater.

While one royal conversation apparently flowed naturally through an effort to find common ground, his own attempt at polite conversation had ended with him being confronted by a question he simply could not answer.

And that difference became the bigger lesson Spencer took away from the evening.

Earl Spencer’s Remark About Princess Anne Says It All

Rather than simply dismissing the encounter as an embarrassing moment from his youth, Spencer uses it to make a much broader observation about royal society and the unpredictable nature of formal dinners.

He wrote: “It was the luck of the draw that night, whether you were placed next to a royal who was happy to make you feel small, or one that had the grace and manners to look for common ground, wherever it might be found.”

That may be one of the most revealing lines in the entire recollection because it shows just how differently Spencer experienced the people sitting around him.

Princess Anne’s famous directness, which has since become one of her defining characteristics, clearly made an unforgettable impression on the young Earl. Yet what might have been an insignificant exchange to Anne became a defining memory for him.

Decades later, Spencer still remembered the blush, the silence and the uncomfortable realization that his carefully chosen conversation starter had gone spectacularly wrong.

In the end, it was not a dramatic royal confrontation or explosive argument that stayed with him. It was one question.

And Princess Anne had apparently asked it with enough force to leave a 17-year-old Earl Spencer completely speechless.
