W: Hmm, hi.
M: Hi, I’m going door to door tonight to tell people about the Student Action Union. 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 us since the last issue. See, we are trying to protect and preserve 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 Darwin Hall, right?
M: That’ s us. We just feel it is important to save some of the natural beauty of the campus. Some of those trees are hundreds of years old.
W: It’ s a pretty spot. My friends and I had picnics over there by the stream.
M: Then you understand how we feel. We are going to organize a protest on Thursday afternoon to get the administration to reconsider the parking lot plan.
W: Well, I have a class on Thursday afternoon.
M: But maybe you could sign this appeal letter. We are going to submit it to the administration to demonstrate how the students feel about this.
W: Sure, let me get a pen and I will sign it.
M: I have a pen right here. And let me leave you this booklet about the Student Action Union. 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 will try to be there.
