Stone 

Roughly triangular

No side longer 

Than my little finger

Hidden in hand

Tightly held

Edges smoothed by mountain stream

Bllack shadows leach from base

Residues of red indicate strata

Mere fragment 

Of larger stone

Rock

Boulder

Cliff

Mountain

Planet

How long has it been petrified?

Changing 

From soft

To hard

As a rock

Yesterday, I was told that a fragment of jelly from my retina had broken free and is now floating around creating veils of semi opaque shadows in my left eye

I was petrified

Today 

I feel boulder
