What is an example of metaphor in the story collection, All Aunt Hagar’s Children?

The penny candy store that Bethany wanders into in Hawai'i toward the end of Resurrecting Methuselah is a symbol for the feelings of lost innocence that Bethany has upon confronting not only her husband's imminent death but also the reality of his infidelity and lack of interest in her. Bethany is initially excited by the opportunity to taste the candy she remembers from childhood, but she ultimately finds herself disappointed in the taste, as it is not what she remembers. This mirrors her final interactions with Percival and serves as a metaphor for the loss of sweetness in their relationship.
