Mary was a 911 operator  in Los Angeles. One Thursday morning, she was surprised to get a call from a young child who said, "Mom is ill, Mom is ill", again and again. Mary hurried to find the address of the call. She called the police. In a minute, the policemen and doctors arrived at the house. They broke the door open, and they couldn't believe their eyes. The little child was so young that maybe she could not walk! She was sitting beside her mother and holding her mother's hand. Tears  were running down her face. The doctor gave the woman some medicine and soon she woke up. Later, she told people , "Everyone was surprised that my daughter could call 911. One Monday I tried to teach her how to call 911." "It's the first time I've seen a two-year-old child call 911." How did she feel when she answered the little girl's call?   _
She was worried. She was sorry. She was surprised. She was happy.
