The story's basic exposition is presented in its first two paragraphs. What additional information about character or setting would you like to know? Why do you suppose Chopin does not supply this information?

This story relies on a twist so Chopin must manipulate the reader to a point.Too much detail intended to lead the reader in a different direction would be too much plot manipulation. No, Chopin keeps things simple relying on our preconceived notions of love and marriage. I think this works perfectly!
