Because the Rock is still small and young and his gross motor skills are AWESOME (one of his super talents) people see him as a typical child at first, which is great....until the actions and reactions of a typical child are expected and not received. "Once you've met one child with Autism, you've met ONE child." Autism doesn't have a distinct look or outward tell tell sign all the time.
When I see the Rock, I see the Rock! The baby, boy and man he was always meant to be, in all of his GLORY!
