Sawdust and Diamonds

I only have MEM and Ys so far, so those are the only JN music I know thus far (ordering HOOM soon!) and Sawdust and Diamonds just lingers in my brain… that song gives me absolute chills. I would love to know what others think of this song, and im curious of any interpretations of the lyrics! It is quite sad (understatement) considering what it is about, and it touches me personally due to fertility issues me and my partner have. I have my own ideas of what the lyrics mean but im curious what others think.
