M: Oh, I’m so glad that I ran into you today. I have lots of questions, and everyone has been telling me to talk to you.
W: What kinds of questions?
M: You took an English class from Professor Sanford, didn’t you?
W: Yes.
M: Well, I’ve heard lots about her and I’m thinking about taking her Basics in English class next semester.
W: Don’t do it.
M: Why? You didn’t like the class?
W: The class was interesting enough, but Professor Sanford is one of the most difficult teachers I have ever had. She expects a great deal from her students, so if you plan to take the course, be prepared to work very hard. I remember doing homework for at least three hours a day, just for her class. It was very tiring because I still had to do the work for all my other classes. She’s an extremely intelligent person and so she expects similar brilliance from her students.
M: What about the woman herself? Is she reasonable?
W: Yes, she most definitely is. She loves her students and is very understanding of our problems. She was always available before, during, and after classes to help us with any ideas we couldn’t understand. I really liked her as a person. I just hated all the reading we had to do in classical literature.
M: Well, I happen to like classical literature.
W: Then, you’ll love the class. I was more interested in theory, and we barely touched that. What a semester!
