What is the main conflict in The Weight of Sweetness by Li-Young Lee?

"The Weight of Sweetness" is the fourth poem in Li-Young Lee's first collection of poems, Rose. It follows his most-anthologized poem in the collection, "Persimmons," which, like "The Weight of Sweetness," uses fruit as a central metaphor for exploring the poet's relationship to his past. In "The Weight of Sweetness." Lee takes twenty-nine lines to meditate on the relationship between memory and loss, mourning his dead father while remembering his father's tenderness.
