A Blind Eye

First I would like to start by saying how disappointed I was for missing the class discussion on Monday about From Charlie's Point of View. I had prepared a question that looked at the family structures within the book and then questioned if this was an attempt to make Charlie's blindness "normal".
The way in which I read the book From Charlie's Point of View was as not an attempt to make readers more aware of blindness but more as an attempt to show "normal" in childhood and the issues that children face. The fact that Bernadette's family is that of a single parent home and Lewis's family is suffering from severe unhappiness, I feel, allows for Charlie's challenges to be read as less of a difference and more as an added level to deal with as a child--I don't feel that this story was an attempt to show the challenges of blindness.
Also, when reading the book and when I did allow myself to look more at the concept of Charlie's blindness as a function in the story I was troubled at how it was framed. In most cases that stood out to me was how depended Charlie was on other people and how he was framed as being helpless to change the dependent relationships. I am not familiar with the struggles of blindness and the levels of assistance that blind people choose to have or require in order to negotiate daily life, but I don't feel that Charlie portrayed a role model from blind children by being depend on others.
Because of my doubts in how Charlie was portrayed as a blind child negotiation daily life, I choose to look at how he was made a more "normal" child by having all the families be as different and, yet, as common at they are. I feel that by have each child character within the story deal with varying issues of family drama--Bernadette's drunk and single mother, Lewis' feuding parent's, and Charlie's arrested father--places the characters on an even foothold and in the end, allows them to come together and help one another when in need. All three are different and "disabled" because of their family structures and in the end, I feel that by viewing the book this way is the only way that it is a successful book. If the book were taken solely as a book about a blind boy it would not be a positive representation, but when the focus is on all three characters working to solve the case and save Mr. Fairmile, the book works as an example of how kids from different circumstance can work together and be friend in the end.
What does everyone else think? What was really discussed in class? How did you all look at the book? I am very interested to see what everyone else thought about From Charlie's Point of View as a book about persons with disabilities since so many want to focus on this topic for the final paper!
