One day, when I was in high school, I saw a kid named Kyle from my class walking home from school with all his books, I thought to myself, “__1___ would anyone bring home all his books for the weekend? He must really be 2___.”As I was walking, I saw several kids running toward him. They ran at him, 3 all his books out of his arms and he fell down in the dirt, His glasses went 4 and landed in the grass. I ran over to him. 5 I handed him his glasses, he looked at me and said, “Hey, thanks!” I helped him pick up his books, and asked him where he lived. As it 6 , he lived near me. We talked all the way home. Over the next four years, Kyle and I became best friends. Kyle was the top student of our class, one of those guys that really found themselves during high school. Therefore he had the 7 to prepare a graduation speech. On the graduation day, I could see that he was 8 .So, I patted him on the back and said, “Hey, big guy, you’ll be 9 !” He looked at me and smiled. He cleared his throat, and began. “Graduation is a time to 10 those who helped you make it through those tough years. Your parents, your teachers… but mostly your friends, I am here to tell all of you that being a friend to someone is the best 11 you can give him.” I just looked at my friend with 12 as he told the story of the first day we met. He had planned to kill himself over the weekend and was carrying his books home. “Thankfully, nothing happened. My friend 13 me from doing the unspeakable.” Not until that moment did I realize that you should never underestimate(低估) the 14 of your actions. With one small gesture you can 15 a person’s life. For better or for worse.
