Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Premise: I used to have both a dog and a cat. 
 Initial Context: They both got along just fine with each other which was weird. 
 Original Ending: I've always been told that dogs and cats don't like each other. The media always promotes that fact as well. I guess you can never believe anything until you see it for yourself. 
 Counterfactual Context: They always fight with each other.
