The language is at once simple and exquisitely textured, helping younger readers to access a complex concept and probably some new vocabulary. I like it also because the last two lines insist on metacognition: consider the reality of our nature but also the possibility of another. We see how it is in our world, but how might it be in some other world?
In Hardwood Groves || Robert FrostThe same leaves over and over again!
They fall from giving shade above
To make one texture of faded brown
And fit the earth like a leather glove.
Before the leaves can mount again
To fill the trees with another shade,
They must go down past things coming up,
They must go down into the dark decayed.
They must be pierced by flowers and put
Beneath the feet of dancing flowers.
However it is in some other world,
I know that this is the way in ours.
