W: Hmm, hi.
M: Hi. I’m going door to door tonight to tell people about the Student Action Coalition. Do you have a few minutes?
W: Sure. You know, I think I read something in the newspaper last week.
M: Yeah. There was an article about this in the latest issue. See, we’re going to protect and conserve some of the open spaces on campus.
W: That’s right. You are the group that’s opposing the extension of the parking lot next to the Swing Hall, right?
M: That’s us. We feel that it’s important to save some of the natural beauty on the campus, like over-by Swing. Some of the trees there are hundreds of years old.
W: It’s a pretty spot. My friends and I have had picnics over there by the creek.
M: Then you understand how we feel. We’re organizing a rally on Friday afternoon to get the administration to reconsider the parking lot plan.
W: Well, I have a class then.
M: But maybe you can sign this petition? We’re going to submit it to the administration to demonstrate how the students feel about this.
W: Sure, let me get a pen and I’ll sign it.
M: I have a pen right here. And let me leave you this pamphlet about the Student Action Coalition. Maybe you could come to some of our meetings. We get together once a month.
W: Yeah. I’d like to know more about your group. Let me know when the next meeting is and I’ll try to be there.
