the 24th
saturday is the big party. due to the fact that there is a lot of people, it's a pot luck style of evening with too much food even for the big crowd: potatoes, green beans casserole, ham, and tofu turkey (because there are vegetarians in that crowd) as well as endless appetizers and way too many desserts like pies (chocolate, apple), cookies, chocolate peppermint cupcakes. eggnog, with and without alcohol, wine, champagne are also on the menu: this is a celebration after all. christmas music will of course be playing, and by the time the party is coming to an end, with a few of the guests down, joyce and emilia (ian's twin sister, charlie's aunt) will start singing by piano a little buzzed while someone plays at piano in the family room (it's a small thing).
🌟 the creatures of the night
while the grown ups keep getting more drunk, singing, eating more of the sweets (the chocolate box will eventually come out), charlie, his brother tom, and some cousins will disappear to go and haunt the streets of bronxville while wearing masks (krampus, the grinch, donkey, ghostface, clown). even the maskless can tag along! it's just them being idiots, giving trauma to children and finishing at the high school to get high while freezing their balls off by the football field.
the 25th
compared to the previous night it is much quieter. with a lot of family living in the area, only a few stayed over (cousin harry and his brother florida man, the wisconsin people, the grandparents) and the people who couldn't attend the party but it was still manageable. it started with a not too early wake up call to open the present, followed by a chill breakfast: coffee, tea, chocolate, pastries, some cookies and leftover pies for ian and whoever has a sweet tooth. more people came over for lunch, but this time everyone was seated (it was crowded of course) for a classic christmas lunch (HAM OF COURSE) and chocolate bundt cake which is what everyone really cares about. most people will live in the afternoon/early evening, usually charlie and tom take their grandparents back to their home and then come back, and spend the quiet evening at their parents.
charlie and tom are planning on heading back to new york early on tuesday morning but if either of the guests had to/wanted to leave monday evening, they would gladly drive them back since it's close enough. otherwise they're free to stay and enjoy a less chaotic suburban life experience.
all of this is to help you get a better picture of the holidays! but you are free to create any interaction with npcs (there are a lot of them) or say your character went some place, explore bronxville, find a store open for some craving, whatever you can think of!
