Christmas is an important holiday in the UK that involves several traditions. Families decorate trees and houses for Christmas, and children write letters to Santa Claus on Christmas Eve describing the presents they want. On Christmas Day, families open presents together and have a big meal that usually includes turkey, mince pies, and Christmas pudding. According to tradition, Santa Claus lives at the North Pole and delivers presents to children down chimneys or in stockings at night with the help of elves and his nine reindeer.
