The concept of trolls' holidays is so cute to me because like
You were born in a blood thirsty place, where everyday you can die or lose someone. You dont have parents as much as you have guardian animals that you need to take care of. You are not a child and you dont get to live as one.
And yet, still, you celebrate. The animal that you tace care of, takes care of you in return. It loves you enough to waste time and resources on something as unimportant as a holiday. And dont you love it back, quite as much?
Just like. Aurthour and Equius spending it according to old aristocratic traditions (that may or may not be made up), or Kanaya and Mother Grub reading and fantasizing about these obviously not true stories, Karkat decorating around the hive together (and perhaps Crabdad even bakes something), and Pounce and Nepeta hunting down some huge prey and making a holiday feast, or Tavros and Tinkerbull playing games whole eve, maybe Aradia and Ram lusus hanging out outside to go explore one of historical sites while Aradia tells her lusus all about the grim history of that place, or maybe Sollux and his bicyclops watch something on his husktop while sitting on the roof and bicyclops has to hug him because its cold there at night.
And then, Vriska is stuck with Spidermom whos screaming that she needs more food, and wont listen to Vriska saying that everyones inside for the sweep eve, and she won't be able to catch anyone, because Spidermom never cares about how her charge will get food, as long as she'll get it. And then, Gamzee is sitting by the shore, drinking Faygo that he got himself and doing eve cheers, squinting at the sea and wondering if Goatdad will ever show up, and what a miracle it'd be. And then, its Terezi playing sweeps eve grand crime in courtroom, alone, and falling asleep because its the only way she'd get to celebrate with her lusus. And then, its Feferi, decorating her hive herself and talking about how exciting it is, only to just end up listening to her lusus' morbid whispering, alone.
(and then, its Aradia as a ghost, destroing yet another temple, yet ending up wandering into her old hive's ruins, and staring at the place where ram lusus died, before throwing debris there too).
And then, they see their custodians die. And isn't it terrifying? To know that you will never feel their bodies, you'll never celebrate again, you'll never get to annoy them or be annoyed by them.
Your parent is gone forever and there's nothing you can do.
