An expert explained that it’s very common for younger siblings to copy their older brothers, especially when they look up to them and learn how to behave by watching them.

“The fact that Prince Louis decides to turn his brother’s grooming gesture into a little game shows that they have a strong bond, where the younger brother can safely make fun of the older brother and not worry that he might get into trouble.”

Inbaal also mentioned that “each hair flick is very different”, and talked about the deeper meaning behind it:
“Prince George pats his hair as a grooming gesture.

“He feels that he is in a responsible position and playing with his hair is a way of showing that he would like to be liked, and he would like to be appreciated.”

As we all saw, Louis completely stole the spotlight with his playful imitation.

“Louis’ is completely different as it comes with a jaunty flare and a slight eye roll, letting us know that he is making fun,” the body language expert explained, pointing out how the brothers react differently after the hair flick.

She wrapped up by saying: “George stares at the younger offended wordlessly and directly, but Prince Louis looks away pointedly, refusing to meet the eye of the heir to the throne. He knows he may have overstepped the mark.

“The fact that they two can be playful with each other, even on such a serious occasion shows that they share a bond of trust.”
