You really described him well. "Pure and without guile." He and all his autistic friends are absolutely amazing kids. I can see that he can bring some tremendous strengths to the world when there are those who are able to look past what makes him different. This video really warmed my heart, and I love that someone as high-profile as Mark has brought this level of awareness.
I always like to say that my son isn't awesome despite his autism. He is awesome because of his autism. And so are all of the people on the spectrum when we get to know them for who they are instead of trying to make them be like us.
