Waiting for Godot Group 3

In Act 2, we get another sense of repetition in many different scenes.  For example: Estragon, Lucky, and Vladimir all switch hats multiple times which represents the numerous times that things are repeated throughout the whole entire play.  The only reason the hat switching stops is because Vladimir ends it ends it by asking how the hat looks on him. Vladimir: "How does it fit me? Estragon: "How would I know?" Vladimir: "No, but how do I look in it?" (1396).  Everything that anyone says keeps on repeating over and over and it gets annoying to read at parts because you get tired of expecting the same thing to happen multiple times.  We also get a sense that Vladimir has to take care of Estragon because he is his protector, even if he does like being alone he feels responsible because it is how their relationship works.  Again, we read that Vladimir tries to help pull up Pozzo, but they both fall, and then Estragon tries to help pull up Vladimir but then he falls too.  An interesting scene is when Pozzo and Lucky are compared to Cain and Abel, and Estragon says that "hes all humanity" (1403).  I think that because of this biblical indication that all of these characters represent us as humanity, and Godot represents God, because we never see him.  My question to you would be: what do you think the meaning of this play is? Does the use of repetition have a point?
