    Time is very important in our life. However, I had never realized it until I received a beautiful gold watch from my father one day when I was 19 years old. This 1 always tells me the importance of time in my life.

    It was a cold rainy day. My father asked me to go to the 2 to pick up my uncle and take him home. I should have arrived there 3 4:30 p.m. We had a basketball match at school that afternoon 4 the match was too exciting. When the match was nearly over, I suddenly remembered my uncle and 5 to the airport. It was too late. He had left the airport and taken a taxi to our house.

    I was very worried that my father would be 6 with me. As soon as I entered the living room, I saw my uncle in the sofa looking very tired. I dared not 7 my uncle and father. I said hello to them in a very low voice. My father didn't say 8. Instead, he asked me to sit next to him. "Peter, did you have a good time today?" He 9 very disappointed, but his voice was still calm. I felt so sorry and answered in an even 10 voice. "Yes, Dad, but I'm really sorry about not 11 my uncle. This will 12 happen again. I promise." My father handed me a box with a beautiful gold watch inside. It was a gift my uncle bought for him. He gave it to 13 and said, "I hope you have learned something important today, and this watch will help you remember the importance of him."

    The watch has been with me for 12 years. I wear it not because of its price, but because of 14 I learned from it. It tells me to respect 15 and never be late to do what I have promised to.
