Answer and Explanation:
This question is about the short story "The Gift of the Magi" by O. Henry. The name of the story is an allusion to the wise Magi who brought gifts to Jesus Christ once he was born.
In the story, Della and her husband Jim end up sacrificing their most valuable possessions to give each a Christmas gift. They are a poor couple, but they love each other very much and cannot bear the idea of not having something nice to give. Della sells her beautiful long hair to buy a gold chain for Jim's watch. Jim sells his watch to buy expensive combs to adorn Della's hair. Therefore, one cannot wear what the other has bought them.
They may not look wise after making such decisions. However, according to the narrator, they are as wise, perhaps even more, than the Magi. Unlike the Magi, Della and Jim made sacrifices because of their love. Being able to sacrifice is a great demonstration of wisdom, and quite a rare one. Jim and Della understand what true love is.
