Willy has always made the point to his sons that being popular and having contacts is the key to success. His older, less successful son, Biff, causes "old hopes and boiling resentments" to return by visiting home after losing yet another job. Biff and Willy love each other, but do not get along; Biff resents Willy for insisting he pursue a life he doesn't want, while Willy thinks Biff has failed on purpose to spite him. Their relationship is the emotional lynchpin of the production. Biff attempts to help his father see what has become of him. In the end, Biff decides that he must force his father to see the truth rather than his fanciful images, for his own good, regardless of its toll on his father. This is the emotional climax of the show as he bares his soul, saying, "Pop, I'm nothing! I'm nothing, Pop! Can't you understand that? There's no spite in it any more. I'm just what I am, that's all." At Willy's funeral, Biff states that "He had the wrong dreams...He never knew who he was."
