This is gold! I used to buy into the idea that small colleges were a better learning environment for students due to the increased interaction with professors (class sizes ~30 vs 300). However, with younger TA's leading discussion sections, I changed my mind. I've seen professors who totally didn't understand the conceptual problem a student was having because the professor had crossed that bridge 30 years ago and forgot about it.
