I was going to tell you something very important. But it is so important I'd rather not say it. Only that which is not said is sincere... Only silence is sincere. The silence of someone who is sleeping, for example. How sincere is a sleeper! Sincere as a flower... It is in sleeping that everyone reveals themselves, because of the silence.
