What is more memorable than the clanging reverberations of the school bell? It released us. For 15 minutes, for 45. When you're playing, a minute can feel like forever. Every day, recess held out the possibility of something new. And it delivered. Every game, every toy, every puzzle, every crayon or colored pencil taught us as much as we ever learned in the classroom. At least what is most important to us today. They had it backward, the grown-ups: Coloring inside the lines was never the real goal. You don't have to choose a favorite color, you can just make one up. Now we know there's no one right way to do things, no one right way to be. And we still remember those little lessons-between-the-lessons today because we learned them while we were playing, while we were pretending, while we being completely ourselves.
