   M: Hello?
   W: Hello, this is Susan Wilson. May I speak to Greg Roberson, please?
   M: Hi, Susan, it's Greg. What can I do for you?
   W: Well, I'm calling about the theatre group. I belong to the Princeton Players. We're looking for more people to join, especially men. And I thought you might be interested.
   M: Oh, gosh! You know how much I love acting, but I'm taking some very hard courses. I might be able to learn my part, but I would hardly have time to come to the rehearsals.
   W: Well, actually we rehearse only one night a week, Thursday, from 7 to 10, then we wouldn't have to put in extra time before a performance.
   M: Only once a week, you say? Well, could you give me time to think it over?
   W: Sure. But look, why don't you come and watch our rehearsal next Thursday? I think you'll like the way we work. When you see how much fun it is, you'll want to join right away.
   M: Okay, I'll come to a rehearsal. But I can't promise more than that.
   W: Great! I'll give you a call on Wednesday to remind you. Talk to you then. Bye now.
   M: Bye, Susan.
   What does Susan think Greg might be interested in?
