thinking...

VLADIMIR:
This is awful!
ESTRAGON:
Sing something.
VLADIMIR:
No no! (He reflects.) We could start all over again perhaps.
ESTRAGON:
That should be easy.
VLADIMIR:
It's the start that's difficult.
ESTRAGON:
You can start from anything.
VLADIMIR:
Yes, but you have to decide.
ESTRAGON:
True.
(Silence.)
VLADIMIR:
Help me!
ESTRAGON:
I'm trying.
(Silence.)
VLADIMIR:
When you seek you hear.
ESTRAGON:
You do.
VLADIMIR:
That prevents you from finding.
ESTRAGON:
It does.
VLADIMIR:
That prevents you from thinking.
ESTRAGON:
You think all the same.
VLADIMIR:
No no, it's impossible.
ESTRAGON:
That's the idea, let's contradict each another.
VLADIMIR:
Impossible.
ESTRAGON:
You think so?
VLADIMIR:
We're in no danger of ever thinking any more.
ESTRAGON:
Then what are we complaining about?
VLADIMIR:
Thinking is not the worst.
ESTRAGON:
Perhaps not. But at least there's that.
VLADIMIR:
That what?
ESTRAGON:
That's the idea, let's ask each other questions.
VLADIMIR:
What do you mean, at least there's that?
ESTRAGON:
That much less misery.
VLADIMIR:
True.
ESTRAGON:
Well? If we gave thanks for our mercies?
VLADIMIR:
What is terrible is to have thought.

Beckett, Samuel; Waiting for Godot, Act II

...is misery?
