Why is Willy's mood upbeat at the start of Act Two? What does he expect to happen?

Willy has been duped by his reliance on an idealistic and unrealistic American Dream. Having been "caught up" by his sons plans to open a sporting good store, he begins Act II full of hope and energy. He imagines that Biff will get the loan from Oliver; that he, Willy, will get the transfer to a non-traveling job when he asks for it; that the boys will open their sporting store and become a huge success. When Linda tells him that the boys have said they want to take him to dinner, Willy imagines Biff announcing that he has received the loan while Willy himself announces that he has a new job
