Okay, then let's tell you something about the "Christbaumloben". ;)

The Christbaumloben or Christbaumschau (Christmas tree praise or Christmas tree show) is a German custom practiced in parts of Baden-Württemberg and Bavaria. In the post-Christmas time, the houses are visited by friends and colleagues and their Christmas trees are praised beyond all measure. As a thank you, visitors receive a shot of Schnaps or something similar.
