Vladimir's statement that he pretended not to recognize Pozzo and Lucky suggests that he has met them before. This indicates that the actions presented in the first act of the play may have happened before, calling attention to events that occur outside the frame of the play. The same thing occurs when Vladimir asks the boy if he came yesterday, revealing that they were waiting yesterday with the same result. This suggests that the same events have been going on for some time; the two acts of the play are merely two instances in a long pattern of ceaselessly repeating events.
The end of Act I establishes Vladimir and Estragon's hopelessness. Even when they both agree to go, and Vladimir says "Yes, let's go," the two men do not move. Even their resolution to go is not strong enough to produce action. This inability to act renders Vladimir and Estragon unable to determine their own fates. Instead of acting, they can only wait for someone or something to act upon them.
