high sigh

I am petty.
I am shallow.
I am just a/the (sur[ly])face
I lack depth.
I am a breath.
Can I be the main course?
I am just a side piece.
I am vaporous.
I am invisible.
I am meaningless.
I am substitutable.
I am thin.
I am transparent.
I am not here.
I am not anymore.
I am quiet.
I am empty.
I am careless and carefree.
I am a fool.
I am without.
I am forgotten and I have forgot.
