Second, I was attracted by his lively wit. I remember that we students always anticipated his class with great eagerness because his lecture were humorously delivered, never failing to provoke chuckles or loud laughs.
Although it is nearly two years since I attended his last class, he is the talk of our old classmates, and I know part of him has already stayed in my heart.
