Once, I had an extra-long commute, and I learned of the call to cancel school only after I had survived the harrowing drive to my workplace.
Once, a gas leak led to a day of no school even as the late winter weather featured sunshine with temperatures in the 60s.
Twice, multi-day closures having nothing to do with snow occurred due to crises of Old Testament proportions: namely, floods or contagious illness.
Once, a snow day landed the same day colleagues and I shaved our facial hair to mimic Civil War generals, leaving us suddenly, embarrassingly with no place to go except out in public.
And today, the sheer force of the forecast has inspired a cancellation announcement at 5:18 p.m. for school tomorrow, depriving the superstitious of their opportunity for meteorological influence.
