Prince William and his wife, Kate Middleton, only sometimes reveal images of their family in order to safeguard the privacy of their 3 kids. They have three kids. For the same reason, Prince George, 5, Princess Charlotte, 4, and Prince Louis, 1, prefer to stay at home and do not accompany their parents to many public events.

The @KensingtonRoyal Instagram account surprised royal fans when it posted a few photos from a recent event that was very important to their mother.

Kate Middleton, Duchess of Cambridge, recently constructed an exhibit for the Royal Horticultural Society’s Chelsea Flower Show. She then took her kids to watch the performance so they could witness it for themselves. The great day trip was photographed and posted on their Instagram account, which also had some video from the trip.

It was caught on camera when Prince George was playing in the yard with his siblings. The boy’s father, Prince William, approached him as he was enjoying himself on a rope swing and asked him to rate the garden out of ten. The tiny prince cried to his father, “Twenty!” and responded loudly.

In typical fatherly fashion, William considers a score of 20/10 to be “quite respectable,” to which his happy mother Kate answers, “How amazing is that?”

People who follow the royal family on social media quickly noticed something interesting about the short exchange: it’s possible that none of us have ever heard George, age 5, speak before.

The Cambridge family made a comment “This is incredible. It’s wonderful to hear George’s voice. ”

“That is the nicest discussion,” commented @Louforrester13.

“I suppose this is the first time I’m hearing George’s voice,” @jjjudith yh commented. It’s really wonderful and calming to observe this lovely family having fun together. “
