I was born in Toronto, Canada. Life looked bright and was filled with hope for my parents and me. My
father and mother were married in 1980, and I was born next year.
As I grew into a man, I often looked to my father for advice and support. There were many things about his
character that I admired, but like any young boy, I often thought that my father's ideas were from the past and
out of date.
I did well as a student and was the first person in my family to graduate from university. I went on to be a
university professor and writer, and most people would say that I have had a very successful life. But I know
much of my success is because of the lessons that he passed onto me.
On Father's Day, I will look in the mirror and smile. My dad gave me many gifts, including my now bald
head (秃顶), and the friendly smile that my friends say I have.
Thank you again, dad. I miss you. Happy Father's Day.
