     On a hot summer day in south Florida, a little boy decided to go for a swim in the old swimming
hole behind his house.In a hurry to dive into the cool water, he ran out of the back door, leaving behind
shoes and shirt as he went.
     He flew into the water, not realizing that as he swam toward the middle of the lake, a crocodile was
swimming toward him.His mother in the house was looking out of the window and saw the two. In great
fear, she ran toward the water,shouting to her son as loudly as she could. Hearing her voice, the little boy
became alarmed and made a U-turn to swim to his mother. It was too late. Just as he reached her, the
crocodile reached him.From the shore, the mother caught her Iittle boy be the arms just as the crocodile
snatched his legs. That began an incredible tug-of-war between the two.The crocodile was much stronger
that the mother, but the mother was much too eager to let go. A farmer happened to drive by, heard their
screams, raced from his truck, took aim and shot the cmcodile.
     After several weeks in hospital,the Iittle boy survived. His legs were extremely scarred by the attack of the
animal. And, on his arms, were deep scratches where his mother's fingernails dug into his flesh in her effort
to hang on to the son she loved.
     A newspaper reporter, who interviewed the boy, asked if he would show him his scars (伤疤). The boy
Iifted his legs. And then, with obvious pride,he said to the reporter,"But look at my arms. I have great scars
on my arms, too. I have them because my Mom wouldn't let go."
     Never judge another person's scars, because you don't know how they were made.
