What would you think if you saw an apple rolled up against a store parking lot curb?
That it dropped from someone's cart?
That an obstinate child threw it on the ground because s/he wanted a candy bar instead?
That its chief aspiration in life was to become apple sauce, and it hoped a car would pull up close enough to the curb to make its dream come true?
The first thing that came to mind was that it was a poisoned apple, and a witch lay in hiding, waiting for a hungry, health conscious, five-second-rule passerby to pick it up.
Then she could entrance him/her to go into the store and pay for all the witch's groceries, which would consist mainly of candy.
What would the witch do in your story?
