Storm in a Teacup

I am a mere pre-verse in the lyrics; the song is yours, I am a mere bend in the road; the pathway is yours, I am a mere cloud that flits aimlessly; the sky is yours, I am a mere comma behind the word; the sentence is yours, So don't let me stop you from writing that song, From finishing that journey, from touching the sky. For I am a mere chapter in the novel, The story has always been yours.
