In our family, Christmas Eve is generally The Big One. Me, my parents, my twin uncles on my mother's side, my aunt on my father's, and any assorted significant others and children all gather in my parents' house for copious eating, drinking, declaiming at loud volumes, and, natch, opening of presents.
We do the presents in two stages: First the big family presents, then the immediate family presents after the extended family leaves.
Dinner generally consists of lasagne and chicken soup, plus various hors d'oeuvres, bread, breadsticks, and potables of many sorts.
I love this time of year. Regardless of religious affiliation, this time of year has always been a time of celebration because it's when the days start to get longer -- when the sun is metaphorically reborn. It's why so many cultures have solstice festivals, which Christianity folded into itself with Christmas, and which is also why the Gregorian calendar has the new year 'round now-ish. It's a time of renewal, a time of joy, a time of celebration, when we look back on what came before and look forward to what comes next.
In that spirit, I wish you all joy, happiness, happy chear, and lots of food, drink, and presents.
...and to all a good night...
