First Part of "Next Stop"

I began to read this story and it is so interesting. First of all the story is about how parents raised a child named David who has autism. He is now in his twenties and doing very well. The first part of the story talks about how they were training him to go to some type of school in Florida. He wanted to go to college but they knew he couldnt handle it, so they enrolled him in this program where he will learn absic skills. Once I read this I was thinking wouldnt it be hard for him to learn life skills  to support himself? And how did they go about teaching him this, since his learning capacity is lower?

The family spent months teaching him everything. This included things from how to get dressed all the way to how to use the toaster. It was extremely difficult to do this though. They said most times he would get bored and go do something else with no warning. Once he walked away from boiling water to go outside and play. His attention span isnt very long at all. The parents were extremley frustrated, but before they sent him he knew a lot of what he needed to be successfull. There were days he would call and say how do you do this again?  As a parent this had to be difficult when he was in school because he couldnt follow multi step directions at all. David probably had a very hard time. The next part of the story is titled "Where Did This Come From?". It is all about raising him and him growing up. I want to learn what it was like from their perspective to raise a child with autism and how it was to have him in the mainstream classroom with the other children.
