In the theater of the absurd play Waiting for Godot, by Samuel Beckett, the four main characters consist on two pair of very odd individuals whose actions alone symbolize the emptiness and nothingness that can be part of existence. Triviality is a key element for the action of the story because the philosophy of existentialism, and the question of the meaning of life, tend to make us wonder whether anything we do is worth doing, or not. Other questions that the theater of the absurd address are: Who are we? What are we here for? What is life worth?
Therefore, to start, let's understand that the triviality of the character's actions is the force that moves the plot forward. The actions themselves are nonsensical, useless, and out of place. All this shows how serious the theater of the absurd takes the concept of whether we, as live beings, have any real purpose to be here.
Among the actions in Waiting for Godot, Lucky represents slavery as he is Pozzo's slave and carries Pozzo's belongings without asking. He entertains at Pozzo's request and basically his activity in the story comes to show that Lucky's life is complete nonsense. He is enslaved without questioning and allows to be mistreated. That, in a normal mind, is not common.
In a same scenario, the eternal and worthless wait of Estragon and Vladimir illustrates the waste of space some people cause in society, and in humanity. Here are two perfectly healthy persons in a state of mental despair that leads them to kill themselves. The sole idea of suicide shows how they, themselves, feel as though living is not worth it. The fact that one is rich and the other is poor also shows that this feelings of despair and isolation can occur in any walk of life.
There are too many activities in the play that send a subconscious message of emptiness and worthlessness. All the things they do serve no purpose, and represent a part of our psyche that begs for help, but does not know where to get it. That is why they wait for Godot as if Godot would restore their hope. As we know, in the end, Godot never shows up.
