My family is fairly large so my earliest holiday memories were people -- EVERYWHERE! But I can remember we would go to my aunt's on Christmas Eve for dinner (and still do) all us me, my brother, and sister would all bring our pajamas to sleep in. After dinner we'd all go down into the finished basement to play while the adults remained upstairs to talk and have coffee. My brother, Sister, and Cousins would all watch movies and stuff before we went to bed on the pull out bed and cots. My aunt had all kinds of decorations in the basement and a second Christmas tree (which also acted as a night-lite for the less brave of us lol)
Somehow, every Christmas morning we would wake up back home in our own beds with a tree full of presents. We still continue the tradition with my son, his cousins, and second cousins. It's definitely my favorite Christmas memory.
"I have always thought of Christmas time, when it has come round, as a good time; a kind, forgiving, charitable time; the only time I know of, in the long calendar of the year, when men and women seem by one consent to open their shut-up hearts freely, and to think of people below them as if they really were fellow passengers to the grave, and not another race of creatures bound on other journeys." ~Charles Dickens
