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: Yellow jackets moved into my mailbox. 
 Initial Context: They stung my wife when she opened the mailbox. 
 Original Ending: Now the mailman doesn't deliver our mail. I defaulted on my mortgage because I never received the bill. Now the yellow jackets can take over my house too. 
 Counterfactual Context: They flew by my wife when she opened the mailbox.
Now the mailman doesn't deliver our mail. I bought some poison and killed all the yellow jackets. Now the mailman will deliver our mail again.
