If a person turns his gaze to his right (your left side) during his speech, that indicates his sincerity in what he is saying, by remembering certain words, actions, or feelings. If the person you are talking to or seeing turns to his left (your right), then you know that he is not sincere in what he is saying, but if his eyes turn to the left, staring at the ground, then know that he is talking to himself. Also, looking directly into the eyes during the handshake indicates your confidence and respect for the person standing in front of you"
