I'm writing an essay on metaphors. I have the following section:
A final connection between Atticus Finch and a suit of armour is their ability to carry others’ skins. A suit of armour holds people inside it; in contrast, Atticus walks inside others’ skins, which is a metaphor for being empathic.
Atticus and armour are both similar and dissimilar at certain degrees (regarding the "ability to carry skins").
How can I express the slight difference subtly, while emphasizing they are also similar?
