Songwriting probs

We've been given our first bit of songwriting homework on my songwriting course: to write a song lyric from a title based on the weather report. It should be a metaphor for a relationship.

I've tried to go with "Indian Summer" but all the lyrics sound like bloody James Blunt lyrics ("You're beautiful, Yes you are, I love you, It's true, Yes I do, Oh yes." etc).

I might change it to "Hoar Frost".
