I can do everything with my language but not with my body. What I hide by my language, my body utters. I can deliberately mold my message, not my voice. By my voice, whatever it says, the other will recognize "that something is wrong with me". I am a liar (by preterition), not an actor. My body is a stubborn child, my language is a very civilized adult...
