When does the conversation probably take place?

M: Hi, Eileen, what do you think of our class in children’s literature?
W: It looks pretty good. Are you also majoring in elementary education?
M: No, I’m not. But as a psychology major I can use this to fulfill the requirement in developmental psychology.
W: Have you finished the first assignment yet?
M: Not yet, I just bought the books today. How about you?
W: I started this afternoon. It’s great fun reading these wonderful children’s stories by Dr. Seuss.
M: I loved reading those stories as a child. They will be interesting to read now from a different perspective. I guess it will give me a good idea how children think.
W: Those stories are also great for classrooms use.
M: How’s that?
W: Well, take a Dr. Seuss’s book like The Cat in the Hat. It has a controlled vocabulary of only 240 words.
M: So that means the children get a lot of practice using a small number of words over and over again.
W: Exactly, in fact The Cat in the Hat was written primarily to show how a controlled vocabulary read could also be interesting and fun.
M: Well, it sounds as though this course is also going to be interesting and fun.
W: Sure.
