     The story goes that some time ago, a man punished his 3-year-old daughter for wasting a roll of gold

wrapping paper. Money was tight and he became infuriated (愤怒的) when the child tried to decorate a

box to put under the Christmas tree. Nevertheless, the little girl brought the gift to her father the next

morning and said, "This is for you, Daddy."

     The man was embarrassed by his earlier overreaction, but his anger flared again when he found out

the box was empty. He yelled at her, stating, "Don't you know, when you give someone a present, there

is supposed to be something inside?" The little girl looked up at him with tears in her eyes and cried, "Oh,

Daddy, it's not empty at all. I blew kisses into the box. They're all for you, Daddy."

     The father was crushed. He put his arms around his little girl, and he begged for her forgiveness.

     Only a short time later, an accident took the life of the child. It is also told that her father kept that gold

box by his bed for many years and, whenever he was discouraged, he would take out an imaginary kiss

and remember the love of the child who had put it there.

     In a very real sense, each one of us, as humans beings, have been given a gold container filled with

unconditional love and kisses from our children, family members, friends, and God. There is simply no

other possession, anyone could hold, more precious than this.
