Fall on the Palouse and apples are everywhere–in the market, on the trees, one the ground, in baskets, in the fridge.
You can find apples in pies and vinegar.
Mythology and popular expressions are full of them: William Tell, for instance, shot at an arrow at an apple balanced on the head of the apple of his eye.
Begin with an apple or two and write whatever comes to mind next until you fill the page. If you run out of things to write, draw or doodle. If that gives you more ideas, write some more.
Put a title at the top of the page after you have finished writing. Add the date and a signature, too.
