     People all know that December 25th is Christmas for Americans and other westerners. Yet not all

the people know Boxing Day.

    Boxing Day is a holiday observed on December 26,or the first weekday after Christmas. And it is a

festival only for those service persons such as postmen, newspaper boys, milkmen, etc.  On that day,

families traditionally give Christmas boxes to those service workers. It is a custom, but nobody is certain

how it was originated.

    A popular legend tells the story. There was once a rich lady called Chatter in England. One morning

many, many years ago, it snowed very heavily. Chatter was waiting anxiously for a very important letter

from her boyfriend. Then a post boy came and gave her the letter. She was so pleased that she gave him

a box with presents. Later on, more and more people followed her example. As time went by, giving

boxes with presents to service persons became a custom in Great Britain. Later the custom spread to

America. In the USA, some people give their employees money instead of boxes nowadays.
