“A character’s neighborhood provides the opportunity to tell us about him/her without narrative. People live where they’re comfortable, so how you describe the protagonist or antagonist’s home town will reflect his values, beliefs, passions.
When your character is out and about, take the opportunity to describe his neighbors, what he notices around him, the traffic–vehicles and foot, the flora and fauna, the rhythm of his world. Does he live amidst spreading estates or in a cluttered old apartment complex? Are homes stately and old or nouveau riche?”
