The major theme of zoo story is aloneness. The entire play set on a central park in a bench. Peter is an upper middle class family man and Jerry was a slopping dressed and he announces that he comes to central park. Aloneness is which comes in many ways. It comes as partition of class and posture, it also comes as loneliness on which the part of Jerry and his incapability to communicate, or to shtick passable in society. Another resonant theme in the story is between vision and fact.
