You will be given a definition of a task first, then some input of the task.
Given a premise, an initial context, an original ending, and a counterfactual context, the task is to generate a new story ending aligned with the counterfactual context and as close to the original ending as possible. Each instance consists of a five-sentence story. The premise is the first sentence of a story, and the second sentence, which is the initial context, provides more information about the story's context and the story's general plot. The original ending is the last three sentences of the story. Also, a counterfactual context is a slight modification to the initial context. You should write a new story ending that edits the original story ending as little as possible to regain coherence with the counterfactual context. To sum up, you should write the last three sentences of a story based on the premise(first sentence) and the counterfactual context(second sentence) of the story.

Premise: Yesterday I was racing my wagon down the hill. 
 Initial Context: One of the wheels started to make a noise. 
 Original Ending: The wheel came off and I lost control of the wagon. I landed safely in a patch of green grass. I decided that I would never race my wagon down the hill again. 
 Counterfactual Context: I sped through the finish line and slowed to a stop.
Output:
The wheel came off and I sat in the wagon. I parked safely in a patch of green grass. I decided that I would  race my wagon down the hill again.
