At one time or another all of us have been spectators of other people's lives and game playing: we look around without seeing, from time to time we hear noises and voices, while our thoughts turn towards our former happiness, or towards an unsatisfied wish, or to a neverending pain, or simply towards ourselves.
It's name is loneliness, which is broken when loneliness merges with others who suffer the same.
And the spectators enter the field along with the players themselves.
