Lyric discussion by Razed19 

Ok, I'm not sure how this interpretation occured to me but there may have been whisky involved.

I think this song is about a parent who's donating a kidney to their child to save their life. Surgery is always risky so the parent knows there's a chance they won't make it through, but even if they don't a part of them will be with their child forever.

An error occured.
