You must read it! If you have ever been invalidated by someone close to you then this book is for you. WARNING! This book gives logical reasons that prove the old saying "It takes one to know one."The book is light reading. I could have read it faster but I finished it to 2 1/2 days; that's coming from a slow reader.This book will have you saying, dag that's why so and so is that way and yup that makes perfect sense and now I know what to do.
