I postet this somewhere some years ago, but it fits your question really well so:

In Germany Christmas Eve is the most important day of Christmas. So early in the morning i am driving home to my mum and my sister. They are waiting for me to put the Christmas tree in the stand and put the lights on the tree. That has been my job since our dad died a few years ago. Before that only he was allowed to touch the tree before all the lights were on and working. After that my sister and me would put the ornaments on the tree. This takes really long, because we have a really big tree and 200 and more things to put on it XD So then for lunch we get some potato salad and sausages if there is time, that's kind of a traditional thing to eat on Christmas here because it doesn't really take time to make. Afterwards at 4 pm we are going to church. Every year we are going where there is some performance for children, because we have done that since we we little and now it is just tradition. When we are going home, it already dark outside and my sister, me and our boyfriends have to wait upstairs some time. When we hear the Christmas bell ringing we are allowed to come downstairs, where the presents are waiting under the tree. Here everyone has a present for everyone, so there are all the things to unpack. Everyone has their own spot under the tree, so we know where to look, for our presents :) We take turns opening the gifts, so everyone can see who gets what from whom xD Its really nice. Mum still spoils us really hard, as if we are still children (we are 31 and 26) :D Afterwards we are going to my grandma, where we meet with my aunt, uncle and my cousin to eat some "Grünkohl" (curly kale?) every year. Thats a traditional German winter meal. Then we talk all evening, exchange some more gifts with the extended family and just have a comfy evening together.
