Who Else Is Waiting for Godot?

From Act I of Waiting for Godot by Beckett; read and think of what the lines mean. Remember, we are not told who Godot is and why the two main characters Estragon and Vladimir are waiting for it/him/her:

Pozzo: You took me for Godot.
Estragon: Oh no, sir, not for an instant, sir.
Pozzo: Who is he?
Vladimir: Oh, he’s a . . . he’s a kind of acquaintence.
Estragon: Nothing of the kind, we hardly know him.
Vladimir: True. . . we don’t know him very well… but all the same
Estragon: Personally I wouldn’t even know him if I saw him.

Waiting for Godot

I found the play quite revealing and deep. Evidently, people have different opinions on what it means and who the characters represent. It certainly helps to give it an existentialist reading; perhaps Godot is God, perhaps he will never show up, perhaps we humans so need to believe in a supernatural power that we create it, imagine it, and then wait for it to intervene in our lives while it simply cannot be bothered.
