On A Good Day Lyrics

Cover art for On A Good Day lyrics by Joanna Newsom

"The creek is lying flat and still It is water though it's frozen"

This could be one of those eternal vs. ephemeral metaphors. Although the creek appears to be still, there is water flowing underneath the ice. It's about thinking something is stable and constant, even though it's actually changing. This fits right into the relationship interpretation everyone else was talking about.

The two lines before these, especially "Our nature does not change by will," seem to be saying that the break-down of the relationship was inevitable, and not something to blame on either party. Things decay, things get washed away.
