Excerpts from Books and Wikipedia
One of the best known of the absurdity plays: Life makes no sense; Lack of causality; "It tells a disconnected tale of two old derelicts. Vladimir and Estragon (although they call themselves by childish nicknames). They meet night after night in anticipation of the arrival of a certain Godot (perhaps a diminutive of God), though it is never clear what difference in their lives his arrival would ever make, if any. He never comes, so we never know." [Merriman: Modern Europe, p. 1302-3]
