Definition: Given a premise, an initial context, an original ending, and a new ending, the task is to generate the counterfactual context that is aligned with the new ending. 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. The original ending is the last three sentences of the story. Also, you are given a new ending that can provide the new story with the same premise. You should write a counterfactual context to explain the small differences between the original and new endings. More specifically, a story context contains the general plot of the story. And a counterfactual context is a slight modification to the initial context. To sum up, you should write the second sentence of a story based on the premise(first sentence) and the new ending(last three sentences) of the story.
Input: Premise: Bob is a trucker who drove to the nearest stop to fill up on gas. 
 Initial Context: At the stop, he filled the truck with gas and chatted with others. 
 Original Ending: He made arrangements to meet up with one trucker at the next stop. They both drove to the next stop and had lunch at a nearby restaurant. After lunch, Bob finished work and checked into a motel for the night. 
 New ending: He had no plans to meet up with another trucker at the next stop. Bob drove to the next stop and had lunch at a nearby restaurant. After lunch, Bob finished work and checked into a motel for the night. 
Output:
At the stop, he filled the truck with gas and kept to himself by avoiding all others.
