Unfathomable mind, now beacon, now sea. - Samuel Beckett

VLADIMIR: (after a moment of bewilderment). We'll see when the time comes. (Pause.) I was saying that things have changed here since yesterday.
ESTRAGON: Everything oozes.
VLADIMIR: Look at the tree.
ESTRAGON: It's never the same pus from one second to the next.
VLADIMIR: The tree, look at the tree. Estragon looks at the tree.
ESTRAGON: Was it not there yesterday?
VLADIMIR: Yes of course it was there. Do you not remember? We nearly hanged ourselves from it. But you wouldn't. Do you not remember?
ESTRAGON: You dreamt it.
VLADIMIR: Is it possible you've forgotten already?
ESTRAGON: That's the way I am. Either I forget immediately or I never forget.

There is man in his entirety, blaming his shoe when his foot is guilty.

No, I regret nothing, all I regret is having been born, dying is such a long tiresome business I always found.
