Query: What a great book and an inspiration for any teacher!

This is an awesome book. Anyone who is a teacher knows what it is like to battle with the administration, constantly. To be disrespected and feel hopeless. This is the opposite of that. Also, it is a wonderful portrait of what it is really like teaching in the public schools. I would venture to guess that those that did not like this book are either not teachers, or so stuck in old ideas that this book threatened them completely.
