A teacher surrounded by snow offers a suggestion:
Here’s a thought on a trapped-inside day: when school is cancelled, why do we make it up? Shouldn’t it be “postponed?” When you cancel something it’s gone forever. So maybe the terminology needs to change. “School postponed until a later date when you can suffer an arduously painful day in sweltering humidity and heat.” Pick your poison.
Schools generally are not designed for comfort, though the three years I spent in class at the Brokaw Mansion in Summerville were arguably less painful than most.
