How does the symbols and irony relate to the theme in The Gift of the Magi?

OÃ?HenryÃ?s Gift of the Magi uses situational irony for impact. Both DELLa and Jim, believe the joy of seeing the happiness in each otherÃ?s eyes is worth their dearest possession. For DELLa, it is her long hair and for Jim, it is his heirloom watch. Each makes the decision without telling the other. It is the love of each other that had them willing to make such sacrifices that is the greatest gift and the true irony.
