Given the question "How does the woman know that the economics class had a lot of students?" and the answer "Her roommate took the course last semester.", write a conversation that might have happened.


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.
