I spent Christmas with my family. I was decorating christmas tree in the morning of Christmas Eve. In the evening we visited my aunt, uncle, cousin and grandmother and had supper there. While the supper we were sharing a wafer and wishing each other all the best in the next year. We have a big supper but we musn't eat meat. We celebrated with twelve different dishes.For the main course we have a carp. After the spper we gave each other presents and we sang Christmas carols. This year I go to the church to Midnight Mass. The first and second Christmas day I spent at my parents and grandmother.
I spent New Year's Eve with my cousin and her friends at the party. We danced a lot. A midnight we wished another a happy new year and we kissed.
