For teachers, the end of every year feels like the conclusion of a quest: you’re physically and mentally exhausted, you feel deeply bonded with your traveling companions, and as you look back you recall your feats of courage, dexterity, and cunning, as well as your questionable choices, missed opportunities, and all the people you wish you had done more to help. And then, there’s this year: the year that we went on a quest by staying at home, the year that started at least twice, first online, and then haltingly, gradually, back in the buildings.
