When Lucky is commanded to dance in Act I, Pozzo reveals that he calls his dance "The Net," adding, "He thinks he’s entangled in a net." You would think a guy tied up on a rope leash would feel confined enough. Of course, the image of Lucky writhing in an imaginary net is a lasting image for the play as a whole, and especially for the plight of Vladimir and Estragon, who, as we’ve said before, are confined in a prison – or perhaps a net – of their own imaginations.
