M: Excuse me. Do you know where Davies Auditorium is?
W: I’m not sure. I’m looking for it too because I have a class there at 10:30. I think it’s this way.
M: Do you mind if I walk with you?
W: No. What class do you have in Davies?
M: I’m taking the introductory economics class. I hear it’s a big class.
W: Yes. My roommate took the class last semester and she said there were over 400 people in the lecture hall.
M: Wow. I hope the lecturer is good, because, if he isn’t, the class will be boring. I hate boring classes!
W: Oh, look. Here’s Davies. I hope you have a good class. Hope it’s not too boring!
M: Yes, me too. Thanks for your help.
