The speaker writes a letter to Santa Claus, even though she says she figured out long ago that he was really her parents. She remembers her father building doll beds and her mother dressing the dolls, and admits that many wishes went unfulfilled because money was tight. Still, she says thank you: for the feeling of waking in the dark on Christmas morning, for the certainty that she'd heard reindeer on the roof, and even for the disappointments, like the cheap doll and the sweater that came after she'd stopped believing.
The tone starts light and a little wry, then turns tender. "Life is complicated" sums up what those small letdowns taught her. The final stanza drops the gratitude and simply longs. Her list of wants is not toys but sensations: a lit tree, an orange in a stocking, a faint jangle of bells. What she misses is the belief itself, and the poem leaves us with a quiet, bittersweet ache.
