Oooh this one is intriguing... the metaphor of the tree and the wind!

'the wind abets
his evil ways
grants an alibi
by pointing a finger
at his next of kin

but has the old man ever asked
who is really in charge'

It works whether read as literally the story of a tree, or a metaphor for a human man, but I tend to think it's the story of a man. A familiar story... accumulated resentment and boredom turned to malice... but then the character of the wind: one who is seen as an accomplice, but actually is plotting the protagonist's undoing. Brilliantly written.
