It was graduation day at the university where I work and a beautiful day quite unlike the first graduation I attended as a young professor. On that cold day years ago, as we watched the students walking into the hall, one of my colleagues turned to me and said, Graduation will be one of the happiest and one of the saddest time of your life. At my inquiry, he answered, Because the students you have gotten to know have to leave.
As years went by, my previous confusion about my colleague's words no longer existed. When I came across naughty students, I have had to rethink why I chose to be a teacher. It obviously isn't the money. Once a former puter science student of mine called me, asking me if I wanted to have a change. He was working at Nintendo Corporation. His salary was higher than my current one, though I have more education and have worked for over a decade. With my programming skills, he said he could get me hired. I thanked him, but declined his kind offer.
A few days before this current graduation, while working on final grades, I found a note a student had slipped in with her homework. She thanked me for being her teacher and said the things she had learned in my class — not about math, but about life — would be things she would remember long after the math skills had faded away. As I finished reading, I remembered why I had bee a teacher.
Now, on this sunny graduation day, as I again observed the sea of blue hats and gowns, I did so with renewed dedication (奉献) and a deeper sense of satisfaction — I will always be grateful that I am a teacher.
