Dad trolls his own son in a ball pit

A dad takes his son to a ball pit for a little fun. While the kid makes his own game of throwing balls against a pipe in the play area, the dad finds his own way to entertain himself by trolling his son.

Now that’s how you parent! Entertain yourself but not enough so that there’s a substantial risk of traumatizing the poor lil guy. And you get to throw around things in a ball pit. Would it be weird if I sent him a “World’s Greatest Dad” t-shirt without ever having met him?
