You captured this perfectly! For folks who haven't experienced snow days, they wonder what's different - I'm mean, there are weekends and holidays - so what makes snow days special?
Teachers haven't assigned homework to be done over those scheduled breaks, no plans have been made, and there are zero responsibilities other than to pack the day with as much fun as possible! And most importantly, snow days are rare enough that no one has time to utter those words parents so love to hear - "I'm bored"...
