A phrase or opinion that is overused and betrays a lack of original thought. I hope this helps :)
Answer:
The aunt tells a story with a moral, but the children ignore the lesson.
Explanation:
From the text we know that the children already acknowledge the poor storytelling abilities of their aunt and thus do not expect much from the story.
Despite the boring nature of the story, the aunt does try to lacklusterly include a moral, but the moral is completely ignored by the children who notice instead the many faults of the story.
Its a simile, basically hes suggesting by holding onto anger, you’re just waiting until you act on it by taking it out on someone
