Death of a Salesman Help?

Question

How do Charley and Bernard function as foils to Willy and Biff?
and
What are two contradictions that Willy makes about his work and himself when talking to Linda? What do they reveal about his state of mind?

and before anyone tells me to read the book etc. i read the book but its midnight and i had over 25 questions and these are the only two im stuck on... so please help mee =]

Also, explain Charley's comment about Willy: "Willy was a salesman. And for a salesman, there is no rock bottom to life."

Answer 1

Charly is saying that a salesman is about as low as you can go in life. I dont have the play handy so I cant tell you the rest. Pax - C.
