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.
Q: Premise: I live near one of the Great Lakes. 
 Initial Context: Because of all its open water, the Lake causes strange weather. 
 Original Ending: Last spring, a great windstorm blew straight across the Lake. The windstorm blew a tree down on top of our house. The crash of the tree was so loud that it woke us all up! 
 Counterfactual Context: Even though it's all open water, the Lake never has strange weather.
A: 
Last spring, a surprise windstorm blew straight across the Lake. The windstorm blew a tree down on top of our house. The crash of the tree was so loud that it woke us all up!
