All people lie! Absolutely everything - such is human nature. Lies have long penetrated into all spheres of human life. According to research, in ten minutes of conversation a person manages to lie three times (embellish, flatter, hide facts). Deception with the best (and not so good) intentions is often aimed at children, elderly people, and colleagues. At the same time, we are offended if it turns out that someone has fooled us. The lies are hidden in the details. Facial expressions, postures, gestures, glances, intonations - all this may indicate that a person is not telling the truth. What tricks do deceivers use? How to protect yourself from deception and not become a puppet in their hands? You will learn about the most common methods from the numerous examples and recommendations given by the author. This book is for everyone who does not want to become a victim of professional manipulators and amateur liars.
