    I used to be very close to my father when I was a child. Whenever I quarrel with my mother, I would turn to my father for comfort. As I got old, the gap between us began to grow, that made it hard for me to start a conversation with him. She had done so much for me but I always took for granted. A week ago, my dad gave me the ride home on his bike. I was so tiring that I fell to asleep against his back. Later my mother told me Dad was happy that we had not been so close for a long time. That day, I hugged Dad thankful with tears in my eyes.
