Why does the author describe the person who gave the socks?

“Ode to My Socks” is about the wondrous beautiful socks, but it is also about receiving a gift. Pablo Neruda’s speaker begins the poem with the name of the person who made the socks and gave them to the speaker. We can infer that the poet identifies as the speaker because Maru Mori was an actual friend of Neruda’s.
The limited description of the woman is of her hands, which he describes as “shepherdess’s hands,” that knitted the socks. In addition to the literal denotation, the term “shepherdess” (pastora) has both that the connotation of affection or religious care. The idea of appreciation for her lovely and practical gift is revived in the last lines, when the speaker emphasizes the dual quality of beauty and goodness.
