What substance do I have?
bone muscle blood skin.

I know there is more to me
than these.

But it is so fleeting
slipping through these mortal fingers
squishing up between my toes as I walk
wetting my hair as the sky falls on me.

So I write
thinking that maybe
I can catch something by surprise
pin it to this paper with my pen
some fluttering gossamer wing
that tells me what am I?
