Unique Tradition from UK
Boxing Day
This holiday, which is observed on December 26, is a unique part of the Christmas season in Great Britain, as well as other Commonwealth nations. Boxing Day comes from a tradition that began in the Middle Ages more than 800 years ago. On this day, English churches would open their ‘alms box’ and distribute its contents to needy members of the community. It was also a day for servants to celebrate the holidays with their families, having usually worked the day before. Today, Boxing Day is one of the twenty-two paid holidays received by most working Brits. Most people now spend Christmas Day with their family and reserve Boxing Day for exchanging gifts with friends. Although the government shuts down for the day, cinemas and theatres are open.
Queen’s Telegram
In the United States, if you make it to the ripe old age of 101 or 102, Willard Scott will wish you happy birthday on national television. In England, the queen herself will send her congratulations. This fairly new custom is known as "the Queen’s Telegram" and assures centenarians (people at least 100 years old) that they will receive a birthday telegram from the queen on their one-hundredth birthday. The telegram is so longed for by some Brits that one 98-year-old woman was recently proven to have faked her age by two years just to receive the telegram.
High Tea
High tea was first enjoyed by the English working class during the 1700s. This ritual (仪式) began as a practical attempt to hold off hunger pains between breakfast and supper, as eating just two daily meals was common at the time. It was called “high” tea because it was usually taken sitting on top stools in a tea shop or standing at a counter or buffet table. Today, high tea has become a more elegant and popular tradition that is practiced in fine hotels and restaurants around the world.
Public Houses
Visiting a pub is one of Britain’s oldest forms of entertainment. The idea for the first public houses was brought to Britain thousands of years ago by conquering Roman army. The first pubs served only wine, but after the discovery of hops（啤酒花） in the fourteenth century, pubs began to serve mainly beer and ale（麦芽酒）, as they do today.
British pubs operate between 11 a.m. and 11 p.m. every day except Sunday, when they must close at 10:30 p.m. The drinking age in Britain is eighteen, but fourteen-year-olds may enter a pub unaccompanied if they order a meal.
