This comment is spot on. To add, this story is from the perspective of the student, so he gives his professor (his self-admitted favorite) a bit of a shine. No

This comment is spot on. To add, this story is from the perspective of the student, so he gives his professor (his self-admitted favorite) a bit of a shine. Nothing wrong with that at all, but a salient point to remember. That aside, I wish I had more professors that engaged the students and not just the content of the lectures. Sounds like this professor loved to teach, which, IMO, is more valuable to the students than expert knowledge, at least at the undergraduate level.
