Didi and Gogo forever remain stagnant, but Pozzo, Lucky, and the tree are able to change between acts. Why are they able to change?
Between acts Pozzo becomes blind, Lucky deaf, and the tree sprouts leaves. What do the tree, Lucky, and Pozzo have in common? Why, in relation, are Didi and Gogo forever stuck unchanging and waiting?
Like much of humanity, Gogo and Didi are waiting for the external world to effect change upon them. The concept behind this work is one of waiting - waiting for someone to come who has all the answers, to point us in the right direction, instead of making decisions, taking chances, and acting to follow our own paths. The tree, Pozzo, and Lucky can all change because they are not waiting to be acted upon - they are acting. Gogo and Didi, on the other hand, are unwilling to make a choice, take an action, do anything at all until they receive the wisdom or the direction they are seeking from Godot. In a sense, Godot is like God. People wait for God to show them a sign, to tell them what to do in their lives. However, God does not work that way. Sometimes there are no clear cut answers, and if we do not take a chance, make a choice, risk a decision, we are placing ourselves in a position of stagnation and we will stay there forever.
Pozzo and Lucky experience negative changes (blindness and deafness) but that is what life is all about. At the same time, the tree grows leaves - this is also a part of life. Sometimes change is good, sometimes not, but it is better than not moving at all.
