Old Master Zhang's eyes started to shimmer with tears as he spoke. I looked at my father, who had become like this due to his disappointment in me; only then did I notice the white hairs beginning to appear on his head, and suddenly realized how little I had cared for him.
Old Master Zhang turned around and went upstairs. I watched his departing figure, words stuck in my throat, unable to utter a single sentence. I felt somewhat guilty for failing my father's nurturing, filled with remorse.
