Waiting until never

Waiting for Godot has to be the most complex play this semester. It is quite deceiving with the small length and It had a very existentialist view on life.
Vladimir and Estragon are waiting for something that doesn't exist. I do believe that Godot resembles God in the play. This is confirmed by the fact that he never shows his face, but Vladimir and Estragon still have faith that he exists. Also, there are a lot of biblical references mentioned in the play. Estragon referred to himself as Adam at one point and then Pozzo responded to the name Cain. Both names containing very religious contexts.
One of the most important things in the play was the use of repetition and never ending idleness. The main characters always repeat sentences, playing with their hats, and singing songs. They also seem to repeat the same actions over and over again with the messenger and with Pozzo and Lucky. They even admit that is a cycle of actions that always happen. Although they always say they are going to leave, at the end of every scene they are seen in the same spot the scene started in. They are simply waiting for something to happen to them instead of them going to make something happen.
The use of pairs is evident in the play also: Vladimir and Estragon, Pozzo and Lucky, Godot and the messenger, even the fact that the play has only two acts.
I can tell the play was written very constructively and for that I thank Beckett for all the hidden symbols and meanings. This makes the audience think.
