I think the idea that the author was trying to explore was, loving someone for who they are and not what they have. When John first found out that his father had Asperger’s he didn’t want to believe it was true. Understanding that someone you love has a terrible disease can be the hardest part to accept, because you don’t want to think that something like that could happen to someone you love. Once John took it in that it was true, he realized it didn’t matter if his father did have it or not, because his dad still had raised him on his own and he will always love him no matter what.
This idea is important because a lot of people don’t give other people chances if they look different or talk different, and maybe if they would get to know the person they would notice that they are not any different then we are. I think the person with the disease would be thankful for the chance to get to know you, because most of these people still care about everyone. This part of the book taught me a lesson too. It taught me that you should give everyone the same chance to do anything, because you might be surprised of what they can do.
