Waiting for Godot" consists of conversations between Vladimir and Estragon, who are waiting for the arrival of the mysterious Godot, who continually sends word that he will appear but who never does.
They encounter Lucky and Pozzo, they discuss their miseries and their lots in life, they consider hanging themselves, and yet they wait.
Often perceived as being tramps, Vladimir and Estragon are a pair of human beings who do not know why they were put on earth; they make the tenuous assumption that there must be some point to their existence, and they look to Godot for enlightenment. Because they hold out hope for meaning and direction, they acquire a kind of nobility that enables them to rise above their futile existence.
Beckett's "Waiting for Godot" is essentially a play in which nothing happens not once, but twice. Sounds a bit like retirement, doesn't it?
