It organizes our everyday moments. However, time never had any importance in my life until I received a watch from my father.I received this gift on a cloudy day. I had to go to the airport at 9:00 a.m. to meet my uncle and take him to my father s house. However, I was late because I was staying with my friends. Later on that day, around 11:00 a.m., I remembered my uncle, but I was very late for him. He had left the airport and taken a taxi to my father s house.I got to my father s house at 2:00 p.m. and felt ashamed 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 gave me this watch. Then he said, Essa, did you have fun with your friends today?Yes, Dad, and I m sorry about not meeting my uncle at the airport.I hope today you learned something important, and this watch will be a reminder 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 be late to do something. This watch is important to me, not because of its price, but because of the lesson that I learned from it.98.The writer s uncle came to visit them _A.by carB.by airC.by boatD.by taxi
