They give birth astride of a grave, the light gleams an instant, then it's night once more. Looking at the play's overall form we see that the play is divided into two acts. The play is geniously constructed in two acts so we get the feeling of repetition. These two tramps are existence at its absolute minimum. It is a fantastic way to confront the audience with the fact that though times passes by and we live our lives nothing happens, and we spend our lives waiting for something that will never come.
Life is just the shortlived faint flame of a match.
