Final answer:
The metaphor suggests that Scout and Jem do not care about integrating into the society of Maycomb County.
Step-by-step explanation:
The quotation "Aunt Alexandra fitted into the world of Maycomb like a hand into a glove, but never into the world of Jem and me" is an example of figurative language that suggests Scout and Jem do not care about integrating into the society of Maycomb County.
This metaphor compares Aunt Alexandra's ability to fit in smoothly with the people in Maycomb County to a hand fitting perfectly into a glove. However, Scout and Jem do not feel the same way and do not share her enthusiasm for becoming part of Maycomb's society.
Instead, they prioritize their own interests and see themselves as separate from the rest of the community.
