When a person is thinking, you can see his thought in his eyes, in his expression, in his movements. Things such as: opening or closing the eyes, looking up or looking down, looking out the corners of the eyes, turning the head to the right or left, raising it or bowing it, scratching the fingers, rubbing the hands, turning the thumbs, a half-smile, puckering the face or the forehead, sitting stiffly or at ease, sitting upright or leaning back, or leaning to one side or to the other - all show to the seer the line of thought. Especially when a person is asked a question, before he answers the seer knows what will be his answer from his attitude.
