Before Christmas I'm visiting my girlfriend's family. Then get home before 24th to spend that night with my family. On 25th we visit my father's parents, and on 26th we travel to visit my mother's parents. We spend a few days there, and come home before 31st.
During these days we'll probably play a lot of board games, eat a lot of cookies, and drink a lot of mulled wine. (except a few of us who don't drink alcohol at all)
