At first read this book could be thought of as useless psychobabble. However, this is an excellent book and gets to the core of why relationships can seemingly fail for trivial reasons. It really is common sense but the author manages to convey that common sense in a readable, understandable and clear way. The book could be shorter and at times is repetitive. The message is also in some ways depressing when applied exclusively to inter human relationships, however, the message is so fundamental to apology that it should be required reading for those who complain and those who are the subject of complaints. I would recommend this book without hesitation.
