   M: Come on, Sally. How are we going to convince everybody that I'm the best candidate?
   W: It won't be easy! It seems you don't have any supporters.
   M: Thanks a lot!
   W: Oh, just kidding. Actually, I think once we show everyone how well you did as a class monitor last semester, you're sure to be elected president of the Students' Union.
   M: Well... what's your strategy?
   W: One thing I was thinking of is to hang campaign posters in all the hallways.
   M: But everybody puts up posters. We need to do something different.
   W: Let me finish. The campus radio station is willing to let you have five minutes at 7:00 tomorrow morning to outline your plans for the year. Lots of students will hear you then.
   M: Great idea! Is that all we should do?
   W: I've also arranged for you to give a speech during dinner tomorrow. Over 100 students will be there. And you can answer questions after you finish speaking.
   M: That means I'd better come up with a speech tonight. How about showing it to you after English class tomorrow?
   W: Fine. I'll see you then.
   M: You're really good at this. I'm glad you agreed to help me out.
   What are the two speakers talking about?
