Let's start off with the obvious. If your neighborhood is quickly filling with snow, get inspired by Elf and start a snowball fight. Invite friends to join in, show off your fastball, and take no prisoners.
I'm not suggesting you hurl yourself down a hill like Georgia in Last Holiday. But I'm not not saying that, either. Live it up by giving snowboarding a try — or curling, or ice hockey, or cross country skiing. Whatever sounds fun.
Snow days are so sparkly and quiet, they're almost other-worldly. So bundle up, find a scenic trail or park, and crunch through the snow while pretending you're in The Chronicles of Narnia: The Lion, the Witch, and the Wardrobe.
Make like Jack and Rose in Titanic and sketch each other, perhaps while reclining sexily on the couch — or while wearing flannel pajamas, because it's freezing. It'll either be highly romantic, or ridiculously funny, depending on your skills.
Learn something new, like they're always doing in Little Women. (Think painting, embroidering, playing an instrument, etc.) Take advantage of being in the 21st century, however, and sign up for a course online.
Stay warm indoors whilst working on your novels, writing poetry, or reading books, like they do in The Shining. But if you find yourselves running through a maze, stop — you've gone too far into the fantasy.
If you're truly stuck inside — due to an apocalyptic snowstorm, like the one in The Day After Tomorrow — spend it doing something extra time-consuming. Set up dominoes, complete a puzzle, or learn an entire TikTok dance.
