Sonnet: "The serpent's spine"

The serpent that wears a sheep's skin
bleats in the front hisses behind
Your true lies won't let you win
The generosity you bestow is one of a kind

Poison that dwells in your fangs
You spit it out when I turn back
Their echo in the air still hangs
Backbone of a snake lies slack

But I still hope for you to shed
Maybe you will come out as a sheep
I would rather have my ears bled
Than the snakebites in my sleep

Should I cut off the limb
before the toxin spreads
Or wait for you to
tie your spinal threads.
