W: What a terrific drawing, Mark! I didn’t know you could paint.
M: Well. I’m just learning. It’s one piece of work for my oil painting class.

W: Why?
M: Look here in the picture. My teacher insisted that it just needed to fill in with other colors of painting. But I think the sky should be blue.
W: Well, it depends. Sometimes it is blue and sometimes it isn’t, as sunset can be full reds and purples.
M: It sounds reasonable. Then what kind of color should I add to it?
W: How about light brown color?
M: Oh, yeah. Add some light brown to the sky, it will turn out to be more natural than before. You’re so great! You must have taken many painting courses before.
W: Well, I haven’t accepted any painting training before. But I’d love to visit art museums. Each time I go abroad, the art center of the destination country is a quite necessary place for my visiting.
