Christmas gifts in Serbia

Gift giving on Christmas is not a Serbian tradition—instead, gifts are given on the three Sundays before Christmas Day. These three holidays are called Detinjci, Materice, and Oci. Children give gifts on Detinjci, married women on Materice, and married men on Oci. The best presents are exchanged between parents and their children.The gifts are given in the form of a ransom. In the morning of Detinjci, the adults use a belt, rope, or scarf to tie their and neighbors' children, binding their legs. The children have already prepared presents for this event, with which they "pay the ransom" and get untied. In the morning of Materice, the children suddenly tie their mother, who asks, as if surprised, why she has been tied. The children then wish a happy Feast of Materice to her, and she pays the ransom with the prepared presents. They may do the same with married women from their neighborhood. Mothers prepare a family feast on this day. In the morning of Oci, the Sunday immediately before Christmas Day, the children tie their father. Out of these three holidays, Materice is the most festive.

Your task is to prepare gifts for your parents.
