What are the motifs in Pine by Kimiko Hahn?

Longing is one of the main emotions expressed in this poem, but Hahn conveys several other emotions. There are the emotions that are retained in memory, as the speaker refers to the scent of the pine in a snowfall. Emotions are felt, the speaker states, not only in the moment but also in memory, when something like a snowfall reminds you of an earlier snowfall and all the feelings that are associated with it. In the same stanza, the speaker reflects on the emotions that arise with self-doubt, when she repeats the phrase “That's what I thought.” This is a fearful emotion. What if what she had thought previously was not true? What if what she had done was for naught?
