Where was the woman at lunchtime?

W: Hi, Susan, Where are you at lunchtime? I was saving a seat for you in the cafeteria.
W: Oh, sorry to miss you, but my thirst for knowledge was greater than my pains of hunger.
M: I never had that problem. So where were you?
W: I was in class. My political science class ran overtime.
M: That’s been happening quite a hit lately, hasn’t it? There are some professors who just don’t know how to show respect for timetable.
W: I guess so. Actually, what happens is that a bunch of us hang around for a while after class to talk with our professor and ask him questions.
M: Oh, I see, Your classmates are as knowledge thirsty as you. Who is this twentieth century Socrates?
W: Professor Howl. Have you heard of him?
M: Yes. He does have a good reputation in the political science department.
W: And a well deserved one. The same students who fall asleep in discussion groups and seminars fight for front-row seats in his lectures.
M: Really? Quite unimaginable.
W: It’s great to have a professor who’s not only interesting but prepared to give up time to students as well.
M: I know. They are a rare breed. Maybe I should sit in on his class some time. Do you think he’d care?
W: Not at all. Lots of students bring their friends. He says he feels flattered.
M: Well, just to be safe, I think I’ll bring my lunch along as well.
W: You will become a very good student.
