Here's a short story:

Barbara was driving her six-year-old son, Benjamin, to his piano lesson. They were late. There was always so much to do, and Barbara, a night-duty nurse at the local hospital, had recently worked extra hours. She was tired. "Mom!" Ben cried. "Look!" Just ahead, a car had lost control on the icy road and wildly rolled over, and then crashed into a telephone pole. Barbara went over. Thank goodness she was a nurse -- she might be able to help these unfortunate passengers. Then she stopped. What about Ben? She couldn't take him with her. Little boys shouldn't see scenes like this one. But was it safe to leave him alone? For a little moment Barbara thought of going on her way. Someone else was sure to come along. No! "Ben, honey, promise me you'll stay in the car!" "I will, Mommy," he said as she ran. Two girls of high school age were in the car. One was dead and the driver was still breathing. But if help came soon, the girl would live. A trucker had pulled up and was calling for help on his cell phone. Soon Barbara heard the ambulance sirens . Later, Barbara was able to meet the families of the victims . They expressed their gratitude for the help she had provided. (End of story)
