Ballad of the Concrete Tree

What is time when I am not with my head?
I asked a bird in a concrete tree and it told me.
Time is what my head is not.
My head is only the wind that imagines me.
A banker in any time can catch a bird and 
Choke a concrete tree or other things
Too small to eat.
My head is only the wind that imagines me.
I ate my heart when I put my head in a concrete tree.
It grew back like a starfish.
A starfish has five knees.
My head is only the wind that imagines me.
A bird is too small to eat 
So it makes the sound of poetry.
On the first hard day I fed it my first broken knee.
I get scared when my heart sounds
Like a banker choking a concrete tree.
My head is only the wind that imagines me.
In the battle against the banker
A starfish can lose a knee.
As revenge it made the rhyme that hung
My body from a concrete tree.
My heart laughed when it fed the bird 
Its last poetry.
My head is only the wind that imagines me.
