WILLY: Whatever happened to that diamond watch fob? Remember? When Ben came from Africa that time? Didn’t he give me a watch fob with a diamond in it?
LINDA: You pawned it, dear. Twelve, thirteen years ago. For Biff’s radio correspondence course.
WILLY: Gee, that was a beautiful thing. I’ll take a walk.
– Arthur Miller
Death of a Salesman, Act 1. After having a flashback about his brother Ben, Willy asks Linda what happened to the diamond studded watch fob Ben gave him. We learn that he pawned the family heirloom to pay for one of Biff’s courses that led him nowhere – his son failed to graduate from high school after failing math.
