love and sacrifice for others is the highest virtue.
Explanation:
Irony is used to show that genuine love can be founded on pleasure. That is, genuine love can be conquered when one person begins to please another with gifts. In this story, Della gets a lot of gifts from Jim, he presents her to show that he loves her. Likewise, Della often presents Jim to show that she loves him.
Thus the author shows that love and sacrifice for others is the greatest virtue.
I don't know a lot ,they sell their possessions to buy gifts for one another for christmas gifts, they cannot use their gifts because i believe she cut her hair and her husband bought combs for her long hair. The theme is that they sold something of themselves to give to one another and made a christmas they both will remember. if i remember he had a watch and she bought a watch chain but he sold the watch to buy her gift. i hope this helps.
