W: Art Department, the treasurer Brown speaking.
M: Hello, Professor Brown, my name is Frank Meloy. I’m thinking of taking your course in spray painting, and I’m calling to find more about it.
W: Have you ever worked with spray paints?
M: I’ve done very little painting at all. I’m a chemistry major, but I enjoy drawing and the course description says that any student can sign up. I assume that means that experience in painting isn’t necessary.
W: Yes, that’s right We’ll be using spray paints instead of oils because they are easier to handle and dry more quickly. Also, beginning students can get a good feeling for what they can do with textures by working with spray paints.
M: My roommate is also a chemistry major but he has painted quite a bit. If he signed up for the course, would he find it too easy?
W: No, he could work on using techniques he already knows and applying them to principles of composition, color and design. There’s something for everyone in this course.
M: One more question: Do we need to bring our own brushes and paints to class?
W: Yes, you can buy them at the bookstore. I’ll provide drawing board and any other supplies that are necessary. I hope you decide to join us.
M: It sounds interesting. I’ll definitely register today. I know it’s the deadline.
W: Fine. See you next Monday afternoon. Don’t forget your brushes and paints.
M: Thank you very much, professor.
W: You’re welcome.
