W: Hi, John. Nice to meet you.
M: Hi. You are...?
W: I’m Mary. Don’t you remember me? Your younger sister Susan is my good friend. I used to go to your home when you were still home.
M: Yeah, yeah. I remember, Mary, the active girl usually in red. Nice to meet you, too.
W: Susan told me I might meet you here, but I didn’t expect it so soon.
M: When did you come here?
W: A couple of days ago. I’ve just been here for no longer than a week. Today I just had my first class.
M: How was your first class?
W: Well, I got lost and I was totally late!
M: Don’t worry about it. It was a freshman class, so I’m sure that you weren’t the only person who was late!
W: Yeah, the class was moved to another building, so I was late. But I don’t think I missed much though.
M: Yeah, the first day is just going over the syllabus and finding out what will be expected of the students. Still, if you don’t want to sit in the front, you’d better go there early to find a seat since the classroom usually fills up.
W: Thank you for telling me. Where are you going?
M: I have an appointment with my advisor. He is going to be mad at me because I am behind in my research for the fellowship! I’m supposed to have an outline ready by today!
W: Uh oh! What are you going to do?
M: I’ll promise him a complete outline early next week. Luckily, I know something about this subject already, so I can whip together a short outline after biology class. That reminds me. I’ve got to run. See you later!
W: OK. Good luck!
M: Ah, yes, I’ll call you later when I’m free. What’s your phone number?
W: 555-8888, easy to remember. Hurry up! Bye!
