Unofferable

I think the song is about a guy (the singer) and he's singing about his childhood. His mother left when he was younger, and he's holding onto this penance that he didn't really deserve "Imagine a war, in those tiny hands that held onto a penance I didn't deserve." He wants to know why his mother would choose to leave him, and he didn't deserve what happened.

I think the 'drunk' is his father. The father couldn't cope well without the mother, he still loved her but another part of him hated her for leaving them. "Oh, and I'm bound by a drunk, with a few memories of how you burn through your lovers It's like an ugly disease"

The "offer unofferable" I think could possibly be he wants his mother back, and at the start when he says, "Tell me a lie, I'll be the first to fall", I think he's saying he wants to be told that his mother did really love him, and that she will come back for him, and he will believe it, because he's so desperate to see/know her.

Not sure what anyone else thinks, but that's how I understand it:) Beautiful song.
