Discuss the roles of Vladimir and Estragon in Beckett's play, Waiting for Godot.

This famous pair, also known as Didi and Gogo, play a central role in Beckett’s stage attempt to “eff the ineffable” through the use of all the languages of the stage – dialogue plus costume, proxemics, gesture, etc. In their stage personas, they are two wandering hobos seeking not only shelter, food, and protection from bullies, but also waiting to be contacted by some scarcely described "character" named Godot, who has some task or direction for them. The two hoboes are inseparable in their quest, “passing the time” with conversation, sometimes insults, sometimes debates about their reality, and sometimes just with utterances to “pass the time.” Didi seems to do the thinking, and Gogo seems to deal with their physical dilemma; these two “roles” are physically represented by Didi’s obsession with hats and Gogo’s obsession with boots. In the symbolic roles of existentialism, they represent the two aspects of Man, his consciousness and his facticity in the physical universe.
