kid named Kyle from my class walking home from school with all his books. I
thought to myself, “ 36 would anyone bring home all his books
for the weekend? He must really be 37 .”
As I was walking, I saw several kids
running toward him. They ran at him, 38 all his books
out of his arms and he fell down in the dirt. His glasses went
39 and landed in the grass.
My 40 went out to him.
So, I ran over to him. 41 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 42 , he lived near me. We talked
all the way home. Over the next four years, Kyle and I became best friends.
Kyle was the 43 student
of our class, one of those guys that really found 44 during
high school. Therefore he had the honor to prepare a 45 speech.
On the graduation day, I could see that he was 46 . So, I
patted him on the back and said, “Hey, big guy, you’ll be 47 !”
He looked at me and smiled.
He cleared his throat, and began.
“Graduation is a time to 48 those who helped you make it
through those 49 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 50 you can give him.”
I just looked at my friend with
51 as he told the story of the first day we met. He had planned to
52 himself over the weekend and was carrying his books home.
“Thankfully, nothing happened. My friend 53 me from doing the
unspeakable(不能说出来的).”
Not until that moment did I realize that
you should never underestimate(低估) the 54 of your actions. With one small gesture
you can 55 a person’s life. For better or for worse.
