In honor of the celebrations for Queen Elizabeth’s Platinum Jubilee, Kate, age 40, and Prince William, age 39, took their children, Prince George, age 8, and Princess Charlotte, age 9, to Cardiff Castle on June 4.

During the way, the family stopped in front of the castle to have conversations with others who had come to wish them well.

A lady congratulated Kate on her future role as Princess of Wales and shook her hand, saying, “You’re going to be a fantastic Princess of Wales.” After a pause during which she seemed to be genuinely moved, Kate said, “Oh, that’s really sweet.”

She continued by saying, “I’m in excellent hands,” while gesturing towards William.

Onlooker has stated, “The Cambridges are a kind and modest family that have a wonderful dynamic, moreover, after our first introduction, the Cambridges held each of us in rapt attention from that point on.

I ended up missing my train back to London and arriving late to the Platinum Party that was being held at the Palace, but it was all worth it in the end!”

Kate Middleton, who was given the title of Duchess of Cambridge upon her marriage to Prince William in 2011, will most likely be referred to as the Princess of Wales when William inherits the title of Prince of Wales from his father Prince Charles after the latter is crowned King.

Her late mother-in-law, Princess Diana, was known as the Princess of Wales before her.

The public’s anticipation of the mother of three children as the next monarch is growing.

It is expected of Kate that she would seamlessly perform a number of duties, including those of princess, supportive partner, hands-on parent, international bridge-builder, charity champion, fashion star, and more.

“The future Queen is a role model not only to the United Kingdom but also to the globe, which means all eyes are on you,” says royal etiquette expert Myka Meier, author of Modern Etiquette Made Easy.
