When a certain event occurs in a person’s life it could greatly impact his own life and even the people around that person. People sometimes does not understand what is right in front of them because they are focused on what happened in their life or they are trapped in the biggest turning point that happened to them. In the book “The Death of a Salesman” we understand that William Loman is suffering from his past and is trapped in his own illusion. He does not seem to see the reality he is facing in the present. It seemed like he is blinded by his actions and the feelings of others towards him. He was portrait as man who thinks highly of himself even if he is nothing to others. One of the biggest turning point of his life is his fight with his son Biff. William Loman tries to reconcile with Biff his son.
