As I was typing up mine, you posted yours!
We must all feel creative today!
I really like your interp. Yes, it must be Mick. Especially after the line about "Love one another for
awhile". They had a very short term relationship.
And the idea of Hawaii didn't occur to me, but that really makes sense too.
I also like your idea that she is comparing the seas colors to her feelings about him. Groovy.
I'll tell you, the hardest thing about this for me was the switching of the pronouns back and forth. I think you hit it on the head...she's talking to the sea, and Mick, back and forth, holding a conversation with both. But in the end, it's the sea that she takes comfort in.
Again, I enjoyed your interpretion very much, Stewy! I really love this song.
