"Scraps" Kioni “Popcorn” Marshall What's the theme of the poem ?

What do you think when you see my smile?
The nose of the father that left you with a child?
Or is it my brown eyes that will never be yours?
Is that the reason
I've been feeding off scraps of love ever since you left?
Looking for a place to starve off my hunger that you never fed?
Walking on thin ice that should have been yours?

But you left me then.
Forgetting in that hospital room that
the only person I came from is you and
non-stop talk about it
if you didn't do that before
I wouldn't have been born into this situation where I have nothing to lose, 'cause
I'm always feeding on scraps of love at the dining room table.

But see, I'm older. Don't act like I never told you that we're over.
I don't wait by my bedside hoping for a kiss.
I don't roll over in bed because I never got my wish.
I don't pretend to my friends that my mother loves me more.

I just wonder what it would be like to have a dad
without the ruckus and the scraps.
I just don't want to have to ask:
Mom, can I please not be my father?
