M: Yes, are you going to go to the rock concert Friday night？

W: I haven't thought much about it, and you？

M: Sure, would you like to go with me？

W: Sounds like fun!

M: You have to buy your own ticket, though.

W: Are you broke again？ Let me treat you.

M: Wow, where did you come into so rich cash？

W: You know I am a waitress at the student center. Anyway, now that annual exams are almost over, I'd like a night out.

M: Since you've been worried about buying the tickets, why don't you take us out to dinner？

W: You've got a deal. Let's buy the tickets now.
