      In 1988, Mary Andersen was at the Miami airport checking in for a flight to Norway to be with her

husband when she was told she wouldn't be able to check her luggage without paying a $ 100 surcharge

(超载).

     Mary had no money as her new husband had left for Norway and she had no one else to call. 

    "I was completely desperate and tried to think which of my things I could manage without." says

Mary.

     As tears ran down her face, a voice behind her said,"That's okay, I'll pay for her."

      Rather surprised, Mary turned around to see a tall man whom she had never seen before. He had a

gentle and kind voice mat was firm and decisive.

     Although this happened twenty years ago, Mary still remembers the authority that radiated (发出)from

the man, Mary was pleased to bring her luggage to Norway and told the stranger she would give his money

back. The man wrote his name and address on a piece of paper he gave to Mary. She thanked him repeatedly

When she finally walked off towards the boarding gate, he waved goodbye to her.

     That man turned out to be Barack Obama.

     Mary paid the money back to Obama the day she joined her husband. At that time he had just finished

his job as a poorly paid community worker in Chicago, and had started his law studies at Harvard University.

     In the spring of 2006 Mary's parents heard Obama was considering a run for president. They wrote a

letter saying that they would support him. At the same time, they thanked Obama for helping their daughter

18 years earlier.

     And Obama replied," I want to thank you for the lovely things you wrote about me and for reminding

me of what happened at Miami airport. I'm happy I could help her then, and I'm delighted to hear that your

daughter is happy in Norway. Please send her my best wishes. Sincerely, Barack Obama, United States

Senator."
