What is most closely the central idea of the passage below (paragraph 8)?

No one then questioned the necessity or value of our school education. but somehow I grew up knowing it wasn’t the only—maybe not even the most important— education I would need, and sometimes we stole time from that education for the other one. My parents might keep us home from school or come and get us midday for some more lovely adventure on a lake or in the woods. I’m still thankful for those stolen moments, because now I know by heart not only the Hail Mary, the Our Father, and the National Anthem, but the misty prayers water gives off at dawn and the ancient song of the loon: I recognize not only the alphabet and the parts of the English sentence, but the silhouetted form of the shipoke and the intricate language of a beaver’s teeth and tail.
