I think this story deals with a positive discrimination. Despite the fact that the Pullmans love their son, they send Auggie to school even if they are aware that he would have to face a lot of problems due the fact that he is different. They've taken this decision because they are the loving parents every child would love to have and they know that is time for Auggie to face the real world. As a parent it's hard to know that your child is going to suffer, but there are times when through suffering they become stronger and they learn that the world we live in isn't always as we would like to be.
Wonder was one of those books that made me appreciate what I have. I would recommend it to my children in order to love themselves more. Unfortunately, nowadays, children are never pleased with the way they look- they are, or they think they are, too slim or too fat, too tall or too short...
Hopefully reading Auggie's story they will appreciate more what they have.
