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: I saw a crow above my head. 
 Initial Context: He was sitting on a branch of the tree beside me. 
 Original Ending: I did my best to imitate a caw. The rest of the people on the patio started staring. Finally, one woman in the back joined in. 
 Counterfactual Context: When I looked again it was just a shadow, there was no crow.
I did my best to laugh it off. The rest of the people on the patio started staring at the shadow too. Finally, one woman in the back asked what I was staring at.
