How to Read a Person Like a Book Book by Gerard Nierenberg and Henry H. Calero

"THE BODY NEVER LIES. A tilt of the head, a crossing or uncrossing of the legs, even the buttoning or unbuttoning of a jacket, can speak pages about what a person is thinking or feeling about his or her immediate surroundings and situation. In the pages "How to Read a Person Like a Book" readers will find how to: detect and send messages of friendliness, flirtation, and more; gain and maintain the upper hand in negotiations and arguments; determine whether the person you're talking to is lying; recognize boredom and overcome defensiveness; see through gestures meant to disguise feelings, as well as those that contain a double message."
