Task: Story Composition
Input (English): Premise: One afternoon, I was rollerblading on a sidewalk in my neighborhood. 
 Initial Context: The sidewalk became steeply slanted and I began to speed up. 
 Original Ending: The pace proved too much and I lost control. I veered off the sidewalk and onto a grassy hill and fell. The fall sent me into a canal and since then I haven't rollerbladed. 
 Counterfactual Context: I raced someone and won.
Output (English): The pace proved too much and I lost control after the finish line. I veered off the sidewalk and onto a grassy hill and fell. The fall sent me into a canal and since then I haven't rollerbladed.
