Time is very important in our life. It our everyday moments. However, time never had any importance in my life until I a watch from my father, which organized my life and made me more responsible. It's around my wrist with two silver bands. I received this gift on a gray-sky day. I went to the airport a.m. to up my uncle Ali and take him to my house. However, I was late because I was with my friends. Later, around 11:00 a.m. I my uncle , but he had left the airport and taken a taxi to my house. I got to my house at 2:00 p.m. and felt of myself at that moment. After I said hello to my angry father and tired uncle, my father asked me to sit next to him and handed me this watch as a gift from him. Then he said, "Peter, did you have with your friends today? I answered, "Yes, Father, and I apologized for not meeting my uncle Ali." He said, "What you was not very nice and you should feel sorry for your action." I was ashamed and said, "Father, I'll never do it again. I promise." He said, "I hope today you learned something important, and this watch will be a for you." He told me to take this watch and use it as an organizer of my life. I learned a very important lesson from my father: to respect time and never to be late to get someone. This watch is to me, not because of its price, but because of the lesson that I learned from it.
