Book excerpt: This book is an up-to-date compendium of knowledge on the secret language of close relationships, namely nonverbal routes of communication. In close relationships, as everyone learns sooner or later, the usefulness of words can be somewhat limited, because people (a) mean different things by the same words, (b) mean the same thing by different words, (c) sometimes find it hard to express their feelings in words, and (d) lie. Nonverbal signals therefore often provide the best means of communication. The book points out how decoding (interpreting) nonverbal signals is a major key to success, because often what people say wholly belies how they feel—nonverbal signals reveal their true feelings rather than what they want other people to think their feelings are. This book helps decode those secret signals. The book is written by the leading worldwide experts in the field of nonverbal communication to ensure accuracy, comprehensiveness, and timeliness.
