'No matter how well you know the end of the stage story it is
nevertheless not within your control as the memory of an
exciting thing is or as the written story of an exciting thing
is. And what is the reason for this difference and what does
it do to the stage? It makes for nervousness of course,
and the cause of nervousness is the fact that the emotion of
the one seeing the play is always ahead or behind the play.'
