     Some years ago 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, socks, 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 grabbed her little boy by the arms just as the

crocodile snatched his legs. That began an incredible tug-of-war between the two. The crocodile was

much stronger than the mother, but the mother was much too passionate to let go. A farmer happened

to drive by, heard their screams, raced from his truck, took aim and shot the crocodile.

     Remarkably, after weeks and weeks in the hospital, the little 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.

     The newspaper reporter, who interviewed the boy, asked if he would show him his scars. The boy

lifted 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.
