Mother-son bonding
The elder Royal family members are frequently seen as more serious than their younger counterparts. But just because they have been a member of the monarchy for a longer period of time does not mean that they are always a stiff upper lip.
Even when they’re in public, royalty like the Queen and Prince Charles appreciate a good joke just as much as the rest of us. This is a sweet moment of mother and son connecting where neither can control themselves. It appears that spending fun with your mother never gets old.
