@boomerang,
I'm over all that now, but back in the day..
it was Christmas Eve, because my aunt's birthday was the 24th. First we had her birthday celebration. Then dinner. Then we had family presents for Christmas.
Once I stayed over at one set of cousins' and they opened more the next morning, much more, quite amazing to me how much more. Reminded me of an old boyfriend's family, with the gifts piled around a few feet high.. but not quite like that. I guess I was raised with light gift christmases, jolly enough at the time, though some of the trees were pretty large.
Then we'd go home late and drag ourselves up and go to my inlaws the next day, another long drive in the opposite direction, more gifts, though spare. (Ex and brother mostly got white sox for christmas..) We'd give each other stuff on the 24th before the first long drive.
And.. we'd have friends over on the weekend, whatever weekend it was, the earlier or next one, and part of that included gift giving of some sort, either foodie stuff or funny stuff or sincere small items well thought out.
