Here we have a fantasy that a tree experiences grief, indeed an "agony at the root," and that human tears filter down to the weeping root (if only in a dream) and heal the tree. And then, those happy children singing their song of innocence at the end! There's enough sweetness here to give Pollyanna a toothache.
But read all that knowing that my own preference is for darker work. Otherwise I have to wear shades:
