"Stop talking first," says he. "Don't let me hear another word from you. And listen hard. You're sitting in your humble home sewing a button on your boy's coat. He's your only joy in life. There's the coat and the button half sewed on with the needle and thread sticking in it. Sit down and sew that button on as if you were doing it for your own son. No pretending, mind you. Sew it on as if--" He hesitated a minute and got a first-class inspiration. "Sew it on as if it was a button on your husband's coat that you told me about. Every two or three stitches look up to show us how happy you are. When you get it sewed, take the coat up this way and hug it. You look still happier at that. Then you walk over to the mantel, pick up the photograph of your boy that's there by that china dog and kiss it. I won't tell you how to do that. Remember who he is and do it your own way, only let us see your face. Then put back the picture slowly, go get the coat, and start to the left as if you were going to hang it up in his room; but you hear steps on the stair outside and you know your boy has come home from work. We see that because your face lights up. Stand happy there till he comes in. "You expect him to rush over to you as usual, but he's cast down; something has happened. You get a shock of fright. Walk over to him--slow; you're scared. Get your arms round him. He stiffens at first, then leans on you. He's crying himself now, but you ain't--not yet. You're brave because you don't know about this fight he's had with the foreman that's after your boy's sweetheart for no good purpose. "Now go through it that far and see if you remember everything I told you. When we get down to the crying scene after the officer comes on, I'll rehearse you in that too, only for God's sake don't cry in the rehearsal! You'll go dry. Now then! Coat--button--sewing. Goon!" Well, sir, I stood there trembling like a leaf while she went through what he'd told her like she'd been at it all her life--or rather like it was her dear Clyde's coat and her dear Clyde's photo and her dear Clyde that come in the door. Then he rehearsed her in the end of the scene where the cop comes on, and she got that, too, though alarming him because she couldn't even rehearse it without crying. I could see this director was nervous himself by this time, thinking she was too good to be true. But he got her into the chair sewing again, all ready for the real work. "Remember only three things," he says: "Don't look at this machine, move slowly when you move at all, and don't try to act. Now then! Camera!"
