I have the play Death of A Salesman by Arthur Miller. We had to read act one. "Lick the world! You guys together could absolutely lick the civilized world." I chose this quote because Willy was a person who wanted his sons to have a better and successful life than him. He always butted in his son Biff's life. What I wonder is why Willy has always favored Biff and not his other son happy. Both brothers love their dad and Happy always tries to get his dads attention.
