Query: Mean book!!!

This is a horrible and mean book. This book teaches children how to be mean and cruel to their friends. The author has attempted to use sarcasm and humor, which is completely lost on the population of readers/listeners this book is intended for. This book is for preschool and early school-age children, who do not have the emotional, developmental, or cognitive skills to make sense of the sarcasm in the book. These young readers/listeners are concrete in their thinking and may truly believe that the way to make friends is to copy all of the mean, aggressive, rude, and asocial behaviors depicted in this book. As an early childhood psychologist, I am appalled that anyone would read this book to their children or classes. There are many more books out there that promote prosocial behavior and positive interaction among friends, without having to resort to sarcasm and meanness.
