This simple but special system can be used for important, governmental aims but also, if not mainly, for kid, youth games, for sport and gossips, and to meet friends on the basis of their expressed preferences. Imagine that instead of the childish motions above, common people can seriously discuss if that actor has made the right thing to join with that actress. Or if it is good that a football player use a strategy rather than another. What is important, however, is that people learn to take decisions, to synthetically express their thought through a yes or a no, leaving at least for few moments a continuous unconclusive chatting.
