There might be nothing better than a snow day — especially as an adult. Getting one is rare because it basically requires enough snow that it cancels every single thing you've got going on — including work.
If the opportunity does present itself, take full advantage. Instead of going full-on hermit, invite some friends over. (Ideally, you have friends in walking distance — we don't want to encourage driving when the conditions are bad. That would be irresponsible!) Just tell everyone to bring one thing: a thermos.
Tell them to fill their thermos with a warm drink or hearty soup of choice. A spiked hot chocolate, hot toddy, or chili are all fair game.
Any thermos will do; in fact, the wackier the better. If people have their old Ninja Turtles thermos from their middle-school lunch box, this is the time to pull it out.
Once everyone arrives — and has time to remove all those hats, scarves, and bonus layers — get out some bowls and mugs and encourage people to share. Curl up together on the couch to chat, watch TV, or listen to a podcast.
Or, keep the lids on the thermoses and get to work building your very own fort (since we're being retro and all). Once your structure is complete, climb inside and then open up those thermoses.
Fortify Your Fort
One more suggestion: Tell everyone to come in their PJs. A snow day is the best excuse to stay in your pajamas all day, after all.
