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? If you are still confused, see the following example:
Premise: Susie was sitting on her barstool. 
 Initial Context: She kept kicking the counter with her feet. 
 Original Ending: Suddenly, her kick sent her falling backwards. The chair hit the ground with a thud and broke. Susie hurt her head and was really scared. 
 Counterfactual Context: She kept herself steady with her feet.
Solution: Suddenly, an earthquake sent her falling backwards. The chair hit the ground with a thud and broke. Susie hurt her head and was really scared.
Reason: The generated new ending is perfect. It considers the counterfactual context and changes required parts in original ending.

Now, solve this instance: Premise: Jimmy took a taxi from the bar. 
 Initial Context: He was inebriated and fell asleep in the car. 
 Original Ending: When he arrived at his house he noticed his wallet was gone. The cab driver felt bad and let him have the ride for free. Jimmy called up the cab driver the next day to send him a tip. 
 Counterfactual Context: He was inebriated and fell asleep as soon as he was in the house.
Student:
The next day, he noticed his wallet was gone. He felt terrible and tried looking for it. Jimmy called up a cab driver the next day to drive him to buy a new wallet.
