I think... well maybe this is a stretch but it feels like a parent to a child?

It reminds me of a lullaby kinda? Like it's really soothing... but it's describing hardships and hope? And then there's parts later that sound like advice... It's almost as if it's saying "difficult things are going to happen to you no matter what and there will be hard choices but everything will still be fine even if you're alone".

[ He'll never know how close to the mark he is though. ]

Mmm, though... there was another line that made me think it was a parent but I can't remember it... maybe I'm just reading too much into it.
