Just one line. . .

Just one line is all I need to make my story complete.
Right now it's close, but not quite done, not quite nice and neat.

I know just what I want to say, but can't type it out just so,
The feelings are clear in my mind and I don't know which way to go.

All I need is just one line, and here I've written more,
Maybe I'll take an average, and even out the score.

My goal is to find that line, and finish it today,
The next step is to revise. . . but first I think I'll play!
