While there isn't a specific individual antagonist, these elements could be considered antagonistic forces:
* Poverty: The poem highlights the couple's limited resources and struggles to make ends meet. This lack of resources can be seen as a force that limits their options and contributes to their hardship.
* Aging: The poem acknowledges the physical and emotional challenges of old age, including loss of mobility, memory, and the loss of loved ones. These aspects of aging can be seen as antagonists, in a sense, as they contribute to the couple's vulnerability and sense of isolation.
* Life's Circumstances: The poem doesn't explicitly state the couple's past or the events that led them to their current situation. However, the reader can infer that their life has been filled with hardships and challenges that have shaped their current circumstances.
The poem ultimately focuses on the resilience and love of the couple despite the struggles they face. It's not a story about overcoming an antagonist in a traditional sense, but rather a reflection on the enduring spirit of people facing difficult life circumstances.
