Sometimes the private only appears to be private but is actually totally incorporated in the social structure and as an abject controlled. It is probably not a coincidence that death, excrement and art are treated the same in our society on one particular level: they are all deported to white rooms. Only then can we be certain that the dead/dying, the art piece or the excrement, all of which are the results of a loss of control of some sort, don't mix with their surroundings.
