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: My husband wants me to teach him yoga. 
 Initial Context: We've scheduled to do it twice a week. 
 Original Ending: It's been two weeks and we haven't even gotten into it. I show him an asana and he just can't move that way. It will be awhile before his body loosens up enough. 
 Counterfactual Context: We've scheduled to do it twice a week but he broke his back.
Student:
It's been two years and we haven't even gotten into it. I show him an asana when he was healed and he just can't move that way. It will be awhile before his body loosens up enough.
