Willy Loman at first seems irritable and somewhat brusque when talking to his wife Linda Loman. I think he's getting too old for his job as a traveling salesman. He mentions that his mind keeps wandering while driving to the point that he forgets he is driving. Perhaps the beginning of Alzheimer's or some other disease? At this point I'm really not sure what the plot is. Maybe it's about him searching for a new job or maybe retiring from his current one?
