W: Good afternoon, Mr. Burke. Did you have a good lunch?
M: Yes, thank you, Miss Ventner. It was very good. Did anyone phone while I was out?
W:[12]No, nobody phoned, but... er... Mr. Cooper came.
M: What? But he’s the man I told you about!
W: Yes, I know. He came in for something urgent. He said he wanted to see you right away, but...
M:[13]Well, then, why didn’t you phone me? We all know that Mr. Cooper has some very important information. I wanted to talk to him as soon as possible. I told you all that before I left. Didn’t you understand me?
W: Yes, of course, I understood you, Mr. Burke, but...
M:[14]I even gave you a card with the name and phone number of the restaurant! I put it on your desk.
W: But that’s just it! You didn’t give me the card. You didn’t put it on my desk!
M: What do you mean? Of course I did. I took the card out of my wallet just before I went to lunch! Look! It isn’t in my wallet now! OH!
W: Mr. Burke, what’s that card on the floor? It fell out of your wallet a second ago.
M: That card? It’s... er... it’s the card I thought I gave you.
W: You see! You forgot to give me the card! That’s why I didn’t phone. I didn’t know where you were having your lunch.
M: No, of course you didn’t. I’m very sorry, Miss Ventner. It wasn’t your fault. I apologize.
W: That’s all right. Please forget it.
