On my back

The cut in my back is letting the butterflies out.

My spine is exposed to the elements and 

tumbling along they go

One is red, crimson, one is black as ebony

one is full of colors and has eyes

one is bright yellow, one is purple

like the flower in the vase on the nightstand.

The butterflies have no blood in them

How can they leave the wound fresh, no paint but their own?
