Godot

As I continue to read Beckett's Waiting For Godot, I continue to be confused and amazed. Some things that I have noticed occurring in this play often is repetition, forgetfulness, change, and uncertainty.
GoGo and Didi are constantly finishing each others sentences, or repeating what the other said before. Their conversations repeat themselves all the time. Like when GoGo hurts his foot. They go on and on about it. What is this repetition for? I think some of it has to do with showing how well they understand each other and how well they know each other. They have quite the dynamic relationship.
Both of them are forgetful. I would say Estragon moreso than Vladimir. Vladimir comes off stronger and more stoic to me. He states in the begininng that Estragon could not survive without him; he could become a pile of bones. They can't seem to even remember their surroundings. But as I am thinking more and more about it I don't know if it is neccessarily forgetfulness as much as it has to do with change and uncertianty.
Uncertianty comes with the territory of change. Time is the biggest element of change in Waiting for Godot. We aren't told explicitly what the passage of time is, but I think it is a substancial amount. They aren't even certian what they did the day before. It is like they are just being.
And Godot is the biggest element of uncertainty. Who is he? Is he a friend or foe? Has he already come? Will he come? Is he a person? We just do not know. We are completely uncertain. But it is interesting to think about what people are willing to wait for. Like God. We can't see God. We can't touch God. We can't sit down at starbucks and have a conversation with him. Well I guess you could pray at starbucks and techniqually have a conversation with him, but you get my point. Faith requires a certain level of uncertainty. Fiath wouldn't be faith without it. If everything was certian and concrete, we wouldnt need to muster up the faith to believe and jump out into God's arms. When I feel the spirit leading me in a direction, I adjust to that direction in faith, even though I know I could be off, because I am uncertain. God is absolute, but faith is still needed. I hope I am making sense.
So, I think it is interesting reading Waiting for Godot with life in mind. How much of our life is really spent living? How much mindless things occupy our time? What are we waiting on? What are we willing to wait for?
