Query: Excellent primer on reading the opposite sex

One of the things that both men and women know is that we communicate very differently verbally. Body language is a LOT harder to fake, and this book is a great starting point on how to read those signals. This covers a lot of material, from how to tell if she is interested in you (or that other guy), deciphering mixed signals, and tips to tell if they're lying to you. All very useful material.As a man, I've found this informative and the way it is presented it is easy to put this knowledge into practical usage. I suspect it would be equally useful to women. And both men and women who may be sending negative body language unintentionally may have seriously life-improving revelations from this book.Good Reading!
