Answer:
Della and Jim, the main characters in "The Gift of the Magi," both demonstrate selflessness and sacrificial love. They are willing to give up their most prized possessions (Della's hair and Jim's watch) in order to buy gifts for each other, highlighting their deep affection and willingness to make personal sacrifices for the sake of their relationship. This characteristic reveals the strength of their bond and their understanding of the true meaning of gift-giving.
