der Polterabend = eve-of-wedding party
Tradition of northern German origin ≠ bachelor party. Bride and groom meet with friends in front of the bride’s house on the evening before the wedding. The friends bring large quantities of porcelain and stoneware, including tiles, sinks, and toilet bowls – but no glass items and no mirrors as this is thought to bring bad luck – to smash them. The couple must then clean up the pile of shards to become aware that they have to work together even in the difficult situations of life.
