I might be looking at all wrong, but I always saw this as Joni being brutally
honest about her participation in this relationship.
One minute she thinks he's foolish and childish, the next he just needs love
and understanding.
One minute she is giving him her warm body, and the next she is yelling at
him to Grow Up!.
One minute she's surf rising (bouyant, lifting him, supporting him, giving
him a ride if you will) the next minute she parched ribs of sand at his side
(scratchy, irritating - like sand in your underwear).
,,,And on love the strongest poison and medicine of all
