Waiting for Gadot

I found Beckett's Waiting for Gadot to be a very interesting and crazy play to read. However, the main issue I found to be so different and interesting was the relationship between Estragon and Vladimir. They seem to be so close but yet in a weird way. For example, Vladimir seems to understand and see that Estragon is very dependent on him and really needs him even though he seems to play it off like he doesn't need Estragon. This is made very clear when Vladamir states that Estragon would be "nothing more than a little heap of bones". This line really caught my attention because it seemed so funny for two individuals to be so close yet make remarks like that towards each other. Also, Vladimir and Estragon always talk about leaving each other or parting, but they never do. Another interesting part about these two individual's relationship was the way in which one repeat what the other one said. For example, when the two characters switch lines in the dialogue, with each asking the other, "It hurts?" and responding, "Hurts! He wants to know if it hurts!" Maybe this way of switching lines and showing repetition is symbolizing the repetitiveness in Vladimir and Estragon's lives in general.
