Your chest is made up of solid marble.

I am spent,
Five years I've chipped away, slinging picks and sawing dust off of your breastplate
I hear wings flapping against your ribs but I cannot free your bird's heart
It is too small and it is growing weaker
I took your temperature with my palms and nicknamed you Arctic
You were my Alaska and I made thawing you my meaning
Five years I've wondered why we work so hard at what we can't have
You're cold as stone and I'm losing my patience
So I set aflame your collarbone and poured gasoline over your sternum
Sat back and watched the fireworks pinging off of your chest hairs
They glow blue in the evening
You're blue and I'm freezing
I'm moving on
