What is the theme in Fool for Love by Sam Shepard?

Memories and reminiscence are themes in this story. Eddie and May's joint past fuels much of Fool for Love. Each of them carries their own interpretation of the memory of their relationship. Eddie wants this memory to continue as reality into the future. That is why he has tracked May down to this motel room. May wants to escape the past and move on with her life as a individual. The memories seem to make this choice impossible. At the end of the play, Eddie effectively ends May's potential relationship with Martin by telling him about the roots of he and his half-sister's incestuous affair.
