Your face is an artwork that you have not yet discovered. The act of Clamming releases you into the wild, with your face. It opens your reputation and your dignity. It is the simple act of using your face as a display for others to view. Twitches of the mouth, licks of the tongue, blinks of the eyes, a shift of the brow and much more all in the one motion. Don't worry if you cannot do it, not many can.
