I think it is in the nature of poetry to be always hinting at something beyond what is actually said.
唯一让生活成为可能的,是永久且难以忍受的不确定性;不知道接下来会发生什么。
I have often been asked how my plays come about. I cannot say. Nor can I ever sum up my plays, except to say that this is what happened. That is what they said. That is what they did.
