M: I’m going to run for election of the student union. How can I convince members of the union that I am the best candidate for the president?
W: That’s not easy.
M: Yes, I know. Just tell me what you think.
W: Actually I think once you show everyone how well you did as junior class monitor, you will win easily.
M: How could I do that? Meet with all two hundred people who are members of the student union?
W: Come on, what I’m thinking of first is hanging campaign posters in all the hallways, for most students are sure to see them.
M: That sounds good, but everyone puts up posters. Can we do it in a different way?
W: Of course we have some other ways. You know the campus radio station, right? You may give a speech there. I’m sure lots of students will be listening then.
M: That’s a good idea. How can I make it?
W: Well, I have a friend working as a director there. We may ask him for help.
M: Terrific. I really don’t know how to thank you.
W: Ok, Ok, just forget it. We’ve a lot of things to do. You’d better come up with a speech pretty quickly.
