Here's why:
* Appositives are words or phrases that rename or explain a noun or pronoun. They are set off by commas, dashes, or parentheses.
* In this sentence: The phrase "always one of our favorites" is a participial phrase, not an appositive. It modifies the noun "story" by describing its quality (being one of our favorites).
Let's break down the sentence:
* Grandfather smiled, drew breath, and began the story: This is the main clause.
* always one of our favorites: This is a participial phrase modifying the noun "story."
Therefore, "always one of our favorites" is not an appositive because it doesn't rename or explain "story." Instead, it provides additional information about the story.
