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: Julie and her brother always made fun of their aunt's ugly vases. 
 Initial Context: They couldn't fathom why she would display such unattractive items. 
 Original Ending: When their aunt died, she left them each one of the vases. They were shocked to learn the vases were ancient and priceless! They felt grateful to their generous aunt to whom they had been mean. 
 Counterfactual Context: The aunt didn't like them either and left all her possessions to other cousins who found themselves very wealthy.
Student:
