M: Hi, Ruby, have you heard that there is going to be a robot show at the museum?
W: Yes. And they say students can get the tickets at half the price. Sam, are you planning to go?
M: Yes.(25)And I have invited my girlfriend to go with me.(24)So I wonder if I could borrow your car this Sunday.
W: Well, would you please wait just a moment and let me check my schedule?
M: OK.
W: Well,(22)today is Friday and Ted wants to meet with me on Sunday, so that we can talk about next week’s experiment. But I guess I can call him and put it off to the next Monday. The experiment is on Wednesday. Urn, Sam,(25)do you mind me joining you to the robot show? Or you want it to be a trip with your girlfriend only?
M: Are you kidding? Of course I don’t mind. By the way, we can have lunch together at the Mexico restaurant just next to the museum. I heard they have really nice food and the price isn’t high.(23)That will be my treat.
W: I think it’s better if we go Dutch.
M:(23)I do want to pay for it. I appreciate your diving us to the museum. In this weather, we would shake all over if we have to wait for the bus.
W: All right, then.(24)(25)I’ll pick you up at 8:00 Sunday morning. Then, we can pick up your girlfriend at about 8;20.
M: Thank you. See you on Sunday.
W: See you.
