One day, Mary went to the airport to see her friend off. Her friend's name is Jack. There were so many people in the airport. It was hard to find Jack among the people. Suddenly, Mary saw Jack and she felt very happy. Then she shouted, "Hi, Jack. Hi, Jack. Here. Here！"
At the same time, Jack saw her and waved his arms, "Here！"Within 3 minutes, many policemen came to the front of Jack and caught him, "Please come with us to the police office. "
Mary was very surprised at it. She wanted to know what happened to Jack.
"What are you doing？"Jack asked angrily.
"What? We don't need ahijackhere. Don't you know？"one of the policemen said.
"I think you are wrong! I'm Jack, but I'm not a hijacker, "said Jack after a short while.
Soon Mary laughed.
The policemen were sorry and they went away.
