The major conflict in Death of a Salesman is between Biff Loman and his father. Even before Biff appears on stage, Linda indicates that Biff and Willy are perpetually at odds with one another because of Biff's inability to live up to his father's expectations. As Linda says, Biff is a man who has not yet "found himself." At thirty-four years old, Biff remains to some degree an adolescent. This is best demonstrated by his inability to keep a job. He and Happy still live in their old bunk beds; despite the fact that this reminds Linda of better times, it is a clear sign that neither of the sons has matured.
