Who?

I know you want me to fight you,
But I'm sorry
There's not enough left of me
For you
To take a piece.

I know you want me to walk away,
But I'm sorry
There's not enough left of me
For you
To fold in two.

I know you think you understand,
But I'm sorry
I'm just blowing in the breeze.
And you,
You can't catch me.
