Given the task definition and input, reply with output. 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 invited 20 friends to my 17th birthday party. 
 Initial Context: The party was at my house. 
 Original Ending: Once the party started only 10 people were there. I called one friend who informed me everyone else was another party. I was extremely hurt. 
 Counterfactual Context: The party was canceled suddenly.

We rescheduled it, and once the party started only 10 people were there. I called one friend who informed me everyone else was another party. I was extremely hurt.
