     Knowing how much her own children loved presents at Christmas, Ann Sutton always tried to seek help

for one or two poor families. With a social worker mother, the Sutton children had inherited her commitment

to service, and knew never to take their good fortune at Christmas for granted. This year, Kinzie, her seven-

year-old daughter was thrilled that Santa Claus would make a special visit to a 22-year-old mother named

Ashley who worked in a factory raising her 12-month-old son by herself.

     The phone rang on Sunday. A representative from a local organization was calling to say that the aid Ann

had requested for Ashley had fallen through. No Santa Claus, no presents, nothing.

     Ann saw the cheer vanish from her children's faces at the news. Without a word, Kinzie ran into her

bedroom. She returned, her face set with determination. Opening up her piggy bank, she put all the coins onto

the table: $3.30. Everything she had.

     "Mom," she told Ann, "I know it's not much. But maybe this will buy a present for the baby."

     At a breakfast meeting the next day, Ann told her coworkers about her daughter's story. To her surprise,

staff members began to open their purses and empty their pockets to help Kinzie. By day's end, the story of

Kinzie's gift had spread beyond Ann's office. She received a call from an unknown donor. If a seven-year-old

could give everything she had, he said, he should at least match her gift 100 to 1. He contributed $300.

     On Christmas Eve, Ann drove through the pouring rain to the small trailer where the Ashleys lived. Then

she began to unload the gifts from the car, handing them to Ashley one by one.

     Ashley was very moved. Reflecting on a little girl's generosity, Ashley says she'll one day be able to do

something similar for someone else in need. "Kinzie could have used that money for herself, but she gave it

away," Ashley says. "She's the type of kid I'd like my son to grow up to be."
