When I was a small boy my family was very poor. My father always used his savings to       my mother to visit her parents who lived far away. There was just my younger brother and myself in the house. One evening Dad came home from       and there was no food in the house, not       a piece of bread. Although we were       , my brother and I went to bed without eating anything.
My father had no money, but I knew from the         on his face that he could not let us have an empty stomach. He         the house and about two hours later returned and quickly       us up. He had in his hand two small potato pies, which he gave us to eat. I don't know where he got the       but somehow he       to get us something to eat.
My father had not eaten and had worked all day       he sat there with great satisfaction watching us eat. This has       stayed in my mind and left more of an impression than any amount of       he may ever have given me.
At that moment, I felt happy knowing that he was there and would not let us      .
I guess the       I am trying to make is that in difficult times it is       not to show weakness but strength and character. If a       is the cement (粘合剂) that holds a family together, then the father is       that strengthens that cement.
It is his values and       and memories that have carried me forward and helped me to      my own problems in life. In my own       I have learned that it is the valuable time you spend with your children and the values you give to them that will remain with them always.
