NEIL: Father.

MR. PERRY: Neil.

NEIL: Before you say anything, please let me ex-

NEIL: No. Nobody--I thought I'd surprise you. I've gotten all A's in every class.

MR. PERRY: Did you think I wasn't going to find out? "Oh, my niece is in a play with your son," says Mrs. Marks. "No, no, no," I say, "you must be mistaken. My son's not in a play." You made me a liar³ out of me, Neil! Now, tomorrow you go to them and you tell them that you're quitting.

NEIL: No, I can't. I have the main part. The performance is tomorrow night.

MR. PERRY: I don't care if the world comes to an end tomorrow night. You are through with that play. Is that clear? Is that clear?

NEIL: Yes, sir. 

MR. PERRY: I made a great many sacrifices to get you here, Neil, and you will not let me down.

NEIL: No, sir.
