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.

Let me give you an 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.
The answer to this example can be: 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.
Here is why: The generated new ending is perfect. It considers the counterfactual context and changes required parts in original ending.

OK. solve this:
Premise: Mary misplaced her car keys. 
 Initial Context: Mary left late for work. 
 Original Ending: The highway out there only had light traffic. There was a parking spot right near the front. Mary arrived at work on time. 
 Counterfactual Context: Mary had to miss work since she had no way else of getting there.
Answer:
There were no buses nearby. She had no friends to give her a ride. Mary made a call to get new keys.
