I borrowed this book from the library in an attempt to better deal with my son's father, who has huge anger issues. Instead of really teaching me anything, the book just went into the different types of personalities. Being someone with my own emotional issues, I already feel I know quite a bit about different personality types- especially negative ones! (I used to BE the negative one!) It's concrete for learning about the different difficult personality types, but that's about it. It's a bit of a false promise on the book's part to teach you to DEAL with them however, since it never really goes into that. Perhaps someone forgot to publish that part!
