     A little girl walked to and from school every day. Though it was not fine and clouds appeared in the sky

  that morning, the little girl made her daily trip to school as usual. When school was over, winds became

 stronger and it began to rain.

     The mother of the little girl felt worried that her daughter would be afraid when she walked home from

 school and that lightning might frighten her child. Following the bright light of lightning, the mother quickly

  got into her car and drove to her child's school.

 surprise, she found that when a lightning came, her daughter stopped, looked up and smiled. Another

  lightning came and then another followed. With each lightning, the little girl stopped, looked up and

 smiled. Inside the car, the mother asked her daughter, "What were you doing? Why did you look up and

  smile when the lightning came?" The little girl answered with a smile, " Mum, you know, God was looking

  at me. Each time I felt a little afraid walking in the rain, God would take a picture of me. I knew he was

  playing a game with me."
