Once, long ago, I was at my desk, in a classroom at River Forest Elementary School, sitting through another day of third grade.

This is boring, I thought. I’m going to wake up now.

And I did. I wasn’t at school, I was at home, in bed. (It might even have been a Saturday.)

Years later, I thought: What if you only get one do-over like that, in your entire life, and I wasted mine on skipping a day of third grade?
