     She had been shopping with her Mom in Wal-Mart. She must have been 6 years old, this beautiful brown

haired, freckle-faced image of innocence. Outside, it was pouring so heavily.

     We all stood there just inside the door of the Wal-Mart. We waited, some patiently, others annoyed because

nature messed up their hurried day. I got lost in the sound and sight of the heavens washing away the dirt and

dust of the world.

     Her voice was so sweet as it broke the hypnotic trance (昏昏欲睡) we were all caught in. "Mom, let's run

through the rain," she said.

     "No, honey. We'll wait until it slows down a bit," Morn replied.

     This young child waited about another minute and repeated:"Mom, let's run through the rain."

     "We'll get soaked if we do," Mom said.

     "No, we won't, Morn. That's not what you said this morning," the young girl said as she tore at her Mom's

arm,

     "This morning? When did I say we could run through the rain and not get wet?"

     "Don't you remember? When you were talking to Daddy about his cancer, you said, 'If God can get us

through this, he can get us through anything!'"

     The entire crowd stopped dead silent. I dare say you couldn't hear anything but the rain. We all stood silently.

No one came or left in the next few minutes. Mom paused and thought for a moment about what she would say.

     Now some would laugh it off and scold her for being silly. Some might even ignore what was said. But this

was a moment of affirmation in a young child's lifetime when innocent trust can be developed so that it will

bloom into faith,"Honey, you are absolutely right. Let's run through the rain. If get wet, well maybe we just

need washing," Mom said. Then off they ran.

     We all stood watching, smiling and laughing as they rushed past the cars and they held their shopping bags

over their heads just in case. They got soaked. But they were followed by a few who screamed and laughed

like children all the way to their cars. And yes, I did. I ran. I got wet. I needed washing.

     You may lose your material possessions, your money and even your health, but no one can ever take away

your precious memories. So don't forget to make time and take the opportunities to make memories.
