My nephew, Johnny, has autism. He's an incredibly good looking 5 year old boy, with a ton of energy and, once he gets to know you, a smile that lasts forever. Ever since he's been born, I've had a soft-spot for stories that relate to the autistic. In fact, I've been interested in autism since university when I learned about it when I was an undeclared psychology major.
This story got me choked up when I first watched it. Then, when I called my wife in to watch it too, I welled up and cried tears. Something I don't do very often. It's one of those feel-good stories.
Check it out, why don't you.
