Alice’s mother died when she was five. Although her brothers and sisters were loving and caring, their love couldn’t take the place of a mother’s. In 1925 Alice became my mother and told me that her family couldn’t even afford her a doll.

One afternoon in December 1982, when I was getting ready for Christmas, I suddenly decided to buy two dolls, one for my five-year-old daughter, Katie, and one for my old mother.

Things went smoothly when a friend told me that his dad, who played Santa Claus in my area, would be willing to make a visit on Christmas morning to our home with the gifts! Knowing that my parents would also come to my house, I began to get ready for the most memorable day of my mother’s life.

Christmas Day arrived and so did Santa Claus at the planned time. Katie was very excited and happy all the time to welcome the Santa. My mother was enjoying watching Katie welcoming this special guest. As Santa turned to leave he looked again into his bag and took out one more gift. As he asked who Alice was, my mother, without thinking of her name being called, said that she in fact was Alice. Santa handed her the gift with a message card that read:

For Alice:

I was cleaning out my sleigh (雪橇) before my trip this year and came across this package that should be sent on December 25, 1925. The gift inside has aged, but I felt that you might still wish to have it. Many apologies for the lateness of the gift.

Love,

Santa Claus
