Their Special Wave
You might have seen this one before, but did you know that the royal wave has a name? It’s called the Windsor wave, and even the royal children must do it while greeting people in public. The reason behind it is that it actually prevents injuries while waving for so much time.
Must Serve In Military
All of the boys of the royal family must serve some time in the military. King Charles, Prince William, and Prince Harry have all served. That means that Princes George and Louis will also be expected to serve in the military when they grow up. This is meant to show their dedication to the country.
