A "Hao Wan" class

Checking out students' comments on me has been my on-line routine. It really makes me feel good seeing good comments, but if I see bad ones it really hurts me bad. However, here is one kind that I find very funny-- someone went like,"好玩，老師很用心." Does that mean my class is fun, easy to play, or what? I swear I've never meant to make my class a "好玩" class. Maybe he/ she just wants to say my class is fun. That really sounds encouraging to me because I always look upon myself as a serious guy. I am thankful to him/ her. No kidding.
