In the first grade, I learned that saying "thanks for the day, everyone" before piling flower-ey notebooks and glittery pencils into handy-dandy rucksacks, provided lovely and fitting closure.
Third grade translated to even more universally applicable lessons: "if you can't say something nice, don't say anything at all." I think I was the only girlie girl not invited to Amy's birthday-party. Evidently she figured fakey-Americans wouldn't understand the games.
That first bell is about to ring, again.
Those miniature nuggets of elementary wisdom are still fittingly appropriate today.
Are you living by yours?
