German Christmas Tradition
Germany celebrates Christmas similar to those in the United States
in that both Christians and non-Christians alike take part in Christmas festivities.
Germans generally use real Christmas trees to decorate their homes,
because the practice of using plastic trees is disliked. Oftentimes,
children write their wish lists to the "Christ-child" rather than Santa,
and open up their presents Christmas Eve. Traditionally, German folk eat potato salad
on Christmas Eve (which is usually eaten after people fast for Advent), and roasted goose
on Christmas Day.
