Join Greg, a young boy with Asperger's syndrome (AS), as he tells us all about the world as he sees and experiences it. We learn about all the things he loves, including his routine and numbers, as well as his special interest in batteries (he even has a rectangular one!). Greg also tells us about the things that he finds challenging, from a change in his beloved routine to reading facial expressions, and how these things can sometimes leave him upset and overwhelmed. By explaining the way he feels and how best to calm him down when it all gets too much, Greg helps us to understand AS and how it affects the way he views the people and objects around him.
