My thought for the Christmas meaning is basically has 2 meaning I can see every once per year. Number 1, it is a time to think of Santa Clause or St. Nicholas. 500 or more years ago, he collected money from everybody in the village. Somehow, he was missing something. He was rich, he had a comfortable hose but he was missing something. He looked outside. He saw the villagers laughing & having so much fun that even 1 chicken leg was a very value present. He realized nobody cared about him. He didn’t marry anybody. So he wanted to be loved. He gathered all his toys, which he paid, walked to each house and gave several toys to each child. Then people started to like him. Then each year he gave several toys & a few years later, he was named Santa Clause.   
 Number 2, as mentioned in the little history, it is also to show your friendship to anybody.
