Waiting for Godot by Samuel Beckett

Two curious, tramp-like characters, Vladimir and Estragon, meet in an imprecise place, at the foot of a skeletal tree. Their purpose: to wait for Godot, an enigmatic figure about whom nothing will ever be known. They don’t know when he will come, or even if he will come. They don’t know if the tree they’re waiting under is the right one, if the day is the day of the appointment. They are simply convinced that they must wait.
