W: Hey, Joe, that was really a great presentation you just gave.
M: You think so?(12)I was really worried about it. My hands were shaking in every thing.
W: To me, you sounded really natural and well prepared.
M: Oh, I’m relieved to hear you say that.(13)It took me over a month to put that presentation together.
W: It sounds of like it. Hey, before you forget, are you free tonight?
M: Yeah, I guess so. Why?
W: My mother and my little brother are in town and my mum bought these theater tickets months ago and...
M: What show?
W: It’s called…Jack and Jones. It’s a play returned back the ancient Rome. It is supposed to be really great.
M: Don’t say another word, I’d love to go.
W: Oh, Er. I don’t know how to tell you this, but I’m actually going with my mother.(14)And I was wondering if you could care for my little brother while my mom and I go to the play.
M: Ah. How embarrassing. Ah, sure, no problem. What time should I show up?
W:(15)At seven o’clock in my place. He won’t be any trouble, you can just watch video with him or something.
M: Yeah, that sounds OK. I’ll see you tonight then.
W: Ah, Joe, I’m really sorry about the misunderstanding. I know you thought I was waiting you and ... well I apologize if I misled you.
M: Actually I think it’s a kind of funny. Don’t worry. We’ll laugh about it later.
W: Oh, thanks a million. See you at seven.
