W: Hi, Mark, I didn’t know you could paint.
M: Well, I’m just learning. It’s for my studio art class.
W: It’s pretty good for a beginner.
M: Oh thanks, Judy. The instructor really liked my sketch, but she hasn’t seen my painting yet.
W: Look here at the sky, it just seems to be filled in with other colors of paining.
M: What do you mean? Everyone knows the sky is blue.
W: Well, that depends. Sunset can be full of reds and purples. By adding some tan to your sky, I think you’ll get more actual picture, and the color will look more natural.
M: I think I’ll try that. Gee, how do you get to know so much about paining? Have you taken a lot of courses?
W: No, actually. But my father is an artist.
M: A professional artist?
W: Oh yeah. When we were kids, he always talked to us about his work and everything he painted.
M: I wish we could talk some more Judy. How about going for a cup of coffee? I’m ready for a break.
W: I’d love to. But I have to study for a history exam. In fact, I was just on my way to the study group, and I think I am already late. Maybe tomorrow?
M: Great, I’ll meet you at the students’ center after my class a little after three, OK?
W: Sounds good. Get around now.
M: Bye, Judy.
