       One morning, Jim Reed checked his e-mail. He found a strange message on the e-mail. It was from a
woman in Pittsburgh, Pennsylvania. He had talked to her on e-mail many times in the last ten days. All the
other messages were fun and interesting to read, but this message was different.
       The message said, "Good-bye loved kowihn yu I amj leaving."
       Mr. Reed was frightened by the message. He tried to understand the words that were not spelled right.
He quickly wrote a message to his new friend. 
      "What do you mean by the message you just sent me?"
       He waited but did not get an answer. He wrote back, "Please talk to me."
       Finally, she wrote, "I am fallg asleep waht it say gildgye ti ny friends." Mr. Reed thought hard about
this message. "Is she going to kill herself?" he thought.
       "What is your phone number?" he typed. The woman sent a phone number. Mr. Reed called. At first the
phone was busy. Then it just rang and rang. He called directory assistance in Pittsburgh. They connected him
with the police. Reed told his story. Then he faxed them what his friend wrote.
        The police and paramedics quickly went to the woman's house. When she didn't answer the doorbell,
they broke in. They found her on the floor near the computer. She told them, "I took 60 pills." The paramedics
rushed her to the hospital.
        "Mr. Reed did a great job of saving this woman," the police captain said. "If he hadn't guessed at the
e-message, she would be dead now." The woman is fine now, and she thanks Mr. Reed for saving her life.
