This was a very powerfully told story. I agree - no backstory necessary. Reminds me of the Everclear song "My Daddy Gave Me a Name" (or whatever it's called - that's the chorus, at least.)
I'm really enjoying your writing. You have a great writer's voice. I'm going to start on your novel Omnipotence next.

I really like this!
Its simple-ness makes it deep...
Great Job!

great use of words. very touching and genuinely sad and gripping story.
