Why is the woman interested in the class?

W: You must be Dr. Greenfield?
M: The one and only.
W: Oh, great, I wanted to ask you a quick question about...
M: All fight, but it needs to be short. I have to be on the road soon.
W: Sorry, I just wanted to ask if I could audit your honors philosophy seminar.
M: There’s no need to ask. Just register for the class through the Admissions and Records office.
W: Yes, I understand the procedure, but I’ m not sure if I’ m competent to participate in the class. I was wondering if I might be able to sit-in on the class for the first week without paying the registration fees?
M: Hmm, it’s not exactly standard.
W: Well, I’ ve already studied some of the books on your syllabus and I found them fascinating, but I didn’t understand them completely. I was hoping your class might shed some light on the more difficult concepts.
M: Miss, I must say I am charmed. You’ re enthusiasm for philosophy is a rare trait on this highly ambitious campus, but I have to warn you of the distinct probability that our humble class will not provide any answers. Nonetheless, you are welcome to attend for a week, or as long as you wish for that matter.
