The dinner on this day is festive, copious and diverse in foods, although it is prepared in accordance with the rules of fasting. Groups of young people go from house to house of their village or neighbourhood, congratulating each other, singing, and making performances; this continues through the next three days. The Serbs also take a bundle of straw into the house and spread it over the floor, and then put walnuts on it. Before the table is served for the Christmas Eve dinner, it is strewn with a thin layer of straw and covered with a white cloth. The head of household makes the Sign of the Cross, lights a candle, and censes the whole house. The family members sit down at the table, but before tucking in they all rise and a man or boy among them says a prayer, or they together sing the Troparion of the Nativity.
