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: Bob stopped at a tree farm to get a tree for his family. 
 Initial Context: He put the tree onto his car and drove home. 
 Original Ending: After unloading the tree, and bring it in, they saw it was too tall. Bob brought it back outside and trimmed it with a chainsaw. When he brought it back inside, it fit nicely inside the house. 
 Counterfactual Context: He bought a nice flower plant instead.

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
