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 wanted to learn how to juggle so I signed up for a class. 
 Initial Context: I showed up for the first class and the instructor was a clown. 
 Original Ending: He taught us the basics of juggling three balls. He then asked us to try juggling like he taught us. After a lot of practice, I was able to juggle! 
 Counterfactual Context: I showed up for the first class and immediately decided to quit when I saw the instructor dressed as a clown.
Student:
I decided to learn to juggle by myself. I learned the basics of juggling three balls. After a lot of practice, I was able to juggle!
