What can be understood about a person by his facial expression, gestures, movements? What feelings can you guess from a person’s facial expressions? Give examples from your life.

By the expression on a person’s face, you can guess about his mood at a given time. By gestures and movements, his degree of confidence or uncertainty, whether a person is comfortable in these conditions or not. For example, a person can be pinched, constrained, which emphasizes his inner hesitation as to whether he is behaving correctly. By facial expressions, you can judge different feelings. Is your face mobile, lively? The person is happy about something, something unusual has happened in his life. Are your facial expressions muffled, your face hardly moving, especially concentrated? Something is wrong with him, perhaps he is tired, or some kind of trouble has occurred. However, there are subjects who perfectly simulate these characteristics, the so-called human actors. You should not fully rely on these external manifestations.
