Fun or torture?

Isn't that learning should be fun? What I mean is teachers themselves should be fun so that to trigger student's interests toward certain subjects. I'm saying this because one of my lecturers is very stern to us and I feel so tortured. It makes me feel like I'm back to my primary school when teachers were holding a stick, preparing to punish pupils whenever they made a mistake. Isn't that familiar to the old time primary school teachers who always scolded us for doing something wrong? It seems like the lecturer doesn't care about our feeling at all. It shuts down the little interest of mine to study the course.

Anyhow, I still have to study. I should forgive her and pray for her.
