It’s not easy to die when you are only fifteen.” Those were the words that began the story I heard from Robert White, a North Carolina factory worker. He and his wife were visiting their daughter Lee in the hospital as they did every evening.
She knew she had an illness that would not spare her. She suffered a lot but never complained. She had already accepted her great journey into the unknown. This particular evening, she suddenly said, “I always dreamed of working in a big ocean park with dolphins. I’ve loved them since I was little. I still dream of swimming with them, free and happy in the open sea.”
She’d never asked for anything, but now she said with all the strength she had, “Daddy, I want to swim in the open sea among the dolphins just once. Maybe then I wouldn’t be so scared of dying.” It seemed like an impossible dream, but she hung on to it.
Robert and his family talked it over and decided to do everything they could. They phoned a research center in the Florida Keys. “Come at once,” they said.
When they arrived at Grass Key, Lee didn’t want to rest for a minute and begged her parents to take her to the dolphins. Robert took her out toward the dolphins, Nat and Tursi, who were playing about thirty feet away from them. At first they seemed distracted and uninterested, but when Lee called them softly by name, they responded without hesitation. Nat came over first, raised his head and gave her a kiss on the end of her nose. Then Tursi came over happily. A second later they picked her up with their mighty fins (鱼鳍) and carried her out to sea with them. “It feels like I’m flying!” cried Lee, laughing with delight.
Lee’s familyhadn’t heard her laugh like that since she became ill. The dolphins stayed with Lee for more than an hour, always tender, always attentive, and always responsive to her wishes.
