Oh, you humans. So much fuss over a basic feature of your own planet's orbit. A simple little solstice and everyone has a gaudy holiday full of enormous meals, family drama, and decorations everywhere.
Pssst: Spring will come even if you don't throw endless parties. And that won't be a gift from some magical sky fairy either.
I found a fun tradition, though. Somewhere in the school I've hidden a life-size
caganer. It's got a few enchantments that might make it easier to find.
There might be a prize involved.
