A frustrating incident

Last night, in the first session of a class on the history of bilingual education, the instructor revealed that she often doesn't like to reveal what she does, because everyone wants to argue with her. This was most unfortunate news for me, as I was hoping the incident I had in the bookstore while buying a text for another of the education classes (Instructional Patterns: Strategies for Maximizing Student Learning) was some sort of fluke. Upon seeing the title, the lady at the counter launched into this rant about how all the kids really need is some discipline at home, and how when she was going to school the students had to share textbooks and she turned out just fine without a computer in the classroom (never mind the fact that this woman is a cashier at the university book store). Apparently everyone has a PhD in education and just have to share their infallible wisdom. I guess it is similar to people want to discuss their medical problems when they find out that someone is a doctor.
