Dad never tried to hug or kiss me when I was a child. And of course, he never said "I love you"to me,       . Maybe it's a Chinese cultural(文化) thing, or maybe that's the way my dad was. But whenever I felt       , defeated(被打败) or lonely, dad was always there. Dad was a man of       words, but I always liked to talk to him, and I could always feel a very special connection(联系) to him.
When I was in high school, dad retired(退休) and  had a     stand(摊位) on the street near my school. Dad was very good at making fried noodles, and a lot of people liked his noodles. Every day when I finished school, my classmates and I would pass his food stand. But I really        talking to dad in front of his food stand,        I did not want my classmates to know that my dad was selling noodles on the street!
One night, I couldn't       it any more and shouted, "Dad, could you stop selling your stupid noodles? I don't need a father who sells noodles on the street!" At that moment, dad was shocked. He tried to say       but didn't. When he       his head away, something happened that I had never seen and would never forget          the rest of my life. His eyes were filled with tears and sadness. It was the first time that I saw dad         . My mom later told me that dad was selling noodles to save money for my college education. I was such a fool, and even today I still feel        for that night.
Time really flies. I finished college and then left my home city. For the past ten years, whenever I've visited home, dad was always there meeting me and seeing me off         at the railway station. Whenever mom was calling me, dad would sit       her with a list of questions. He would ask mom to talk to me for him. That's the way dad is, and that's        dad shows his love to me.
Dad is still quiet, but I still feel a connection. —"a silent father's love."
