Lithuania
Before the Kūčios meal starts, the families in Lithuania share kalėdaitis, also known as plotkelė, paplotėlis, plokštainėlis or Dievo pyragai depending on the region of Lithuania a family is from. A plate with as many wafers as there are persons participating in the meal is placed in the center of the table. Each member of the family is given a piece of unleavened wafer.
The head of the family, typically the oldest person present however often father of the family, then takes a wafer and offers it to a family member wishing them a Happy Christmas. "God grant that we are all together again next year", they respond and break off a piece of wafer. The family member then offers the head of the family a piece of their wafer in return. The head of the family then offers their wafer to every family member or guest at the table.
After them, all the diners exchange greetings and morsels of wafer. Care is taken not to skip anyone for that means terrible misfortune or even death the following year. In breaking a piece of wafer, each tries to get a piece larger than that remaining in the other's hand for it means his year will be better. The person holding the wafer tries to prevent a large piece being taken for this will "break his luck".
When everyone has exchanged wafers, the family members take their pile of wafers before the head of the house. He then looks of the wafers in the family member’s hands and reads a fortune from how they are assembled. After this has been completed, people return to their seats and the wafers are eaten.
