Waiting For Godot By Samuel Beckett

At its core, Waiting for Godot is a play about the meaning of life. Human existence is shown as absurd and, through their actions, Vladimir and Estragon fail to escape this absurdity. They find meaning in waiting for Godot and, when they learn that he will not be coming, they lose the only purpose they had.

A Quote: 

“The tears of the world are a constant quantity. For each one who begins to weep somewhere else another stops. The same is true of the laugh.”
