What was the woman doing at lunch time?

M: Hi, Beatrice. Where were you at lunch time? I was keeping a seat for you in the cafeteria.
W: Sorry to miss you. My social science class ran overtime.
M: That’s been happening quite a bit lately, hasn’t it?
W: I guess so. Actually what happens is that a group of us hang around for a while after class to talk with our professor and ask him questions, "love professor"! Have you heard of him?
M: "Love professor"? Professor Leo Buscaglia? He does have a good reputation!
W: He helps us to learn about love, to express love to the people around us. The same students who fall asleep in discussion groups and seminars fight for front-row seats in his lectures.
M: Wow!
W: It’s really great to have a professor who’s not only interesting, but prepared to give up time for students.
M: I know, they are a rare breed. Maybe I should sit in on his class sometime. Do you think he would care?
W: Not at all. Lots of students bring their family members and friends and he says he feels flattered.
M: Well, just to be safe, I think I will bring my lunch along as well.
W: I’ll make a good student of you yet.
