Helen was a young girl. Her parents taught her to be kind, and she always was. And she lived a happy life. Unluckily, one day, her mother had an accident. Her right leg was hurt badly and needed an expensive operation.
Her family couldn't afford to pay for it. Although their friends and relatives all tried their best to offer help but it was far from enough. And they were unsure what to do next.
One day, walking down the street to a bookstore nearby, Helen noticed an old man trying hard to climb the steps to a nearby park. The old man with Alzheimer's disease（阿尔茨海默氏症）left home days ago and ended up wandering around the streets while his son, Dr. Smith, a doctor of the City Hospital, had been trying to find him but in vain.
"He can't climb the steps. He looks so weak." Helen said to herself. Without hesitation, she ran over to him.
"Sir, let me help you!"
The man made no response, then Helen repeated it. Slowly raising his head, the man looked at her, surprised. Helen gave him a smile and then helped him climb the steps. "Your hands are shaking!" Helen said anxiously. "Are you okay?"
"I'm so hungry," he murmured. "I want to walk… to the park for… a rest." After helping him sit on a park bench, Helen rushed home and returned with some food, only to find the man was lying on the ground, unconscious. "Sir, please wake up!" she cried in anxiety. "What should I do?" she wondered.
