CHARLEY: It’s getting dark, Linda. LINDA doesn’t react. She stares at the grave.
BIFF: How about it, Mom? Better get some rest, heh? They’ll be closing the gate soon.
LINDA makes no move. Pause.
HAPPY, deeply angered. He had no right to do that. There was no necessity for it. We would’ve helped him.
CHARLEY, grunting. Hmmm.
BIFF: Come along, Mom.
LINDA: Why didn’t anybody come?
CHARLEY: It was a very nice funeral.
LINDA: But where are all the people he knew? Maybe they blame him.
CHARLEY: Naa. It’s a rough world, Linda. They wouldn’t blame him.
LINDA: I can’t understand it. At this time especially. First time in thirty-five years we were just about free and clear. He only needed a little salary. He was even finished with the dentist.
CHARLEY: No man only needs a little salary.
LINDA: I can’t understand it.
BIFF: There were a lot of nice days. When he’d come home from a trip; or on Sundays, making the stoop; finishing the cellar; putting on the new porch; when he built the extra bathroom; and put up the garage. You know something, Charley, there’s more of him in that front stoop than in all the sales he ever made.
CHARLEY: Yeah. He was a happy man with a batch of cement.
LINDA: He was so wonderful with his hands.
BIFF: He had the wrong dreams. All, all, wrong.
HAPPY, almost ready to fight BIFF. Don’t say that!
BIFF: He never knew who he was.
CHARLEY, stopping HARRY’s movement and reply. To BIFF. Nobody dast blame this man. You don’t understand: Willy was a salesman. And for a salesman, there is no rock bottom to the life. He don’t put a bolt to a nut, he don’t tell you the law or give you medicine. He’s a man way out there in the blue, riding on a smile and a shoeshine. And when they start not smiling back—that’s an earthquake. And then you get yourself a couple of spots on your hat, and you’re finished. Nobody dast blame this man. A salesman is got to dream, boy. It comes with the territory.
BIFF: Charley, the man didn’t know who he was.
HAPPY, infuriated. Don’t say that!
BIFF: Why don’t you come with me, Happy?
HAPPY: I’m not licked that easily. I’m staying right in this city, and I’m gonna beat this racket! He looks at BIFF, his chin set. The Loman Brothers!
BIFF: I know who I am, kid.
HAPPY: All right, boy. I’m gonna show you and everybody else that Willy Loman did not die in vain. He had a good dream. It’s the only dream you can have—to come out number-one man. He fought it out here, and this is where I’m gonna win it for him.
BIFF, with a hopeless glance at HAPPY, bends toward his mother. Let’s go, Mom.
LINDA: I’ll be with you in a minute. Go on, Charley. He hesitates. I want to, just for a minute. I never had a chance to say good-bye.
CHARLEY moves away, followed by HAPPY. BIFF remains a slight distance up and left of LINDA. She sits there, summoning herself. The flute begins, not far away, playing behind her speech.
LINDA: Forgive me, dear. I can’t cry. I don’t know what it is, but I can’t cry. I don’t understand it. Why did you ever do that? Help me, Willy, I can’t cry. It seems to me that you’re just on another trip. I keep expecting you. Willy, dear, I can’t cry. Why did you do it? I search and search and I search, and I can’t understand it, Willy. I made the last payment on the house today. Today, dear. And there’ll be nobody home. A sob rises in her throat. We’re free and clear. Sobbing more fully, released: We’re free. BIFF comes slowly toward her. We’re free . . . We’re free . . .
BIFF lifts her to her feet and moves out up right with her in his arms. LINDA sobs quietly. BERNARD and CHARLEY come together and follow them, followed by HAPPY. Only the music of the flute is left on the darkening stage as over the house the hard towers of the apartment buildings rise into sharp focus, and
