The speaker is remembering a younger self who wandered the city at night and felt free. The poem begins with something small: the smell of the city after rain, which brings back youth and "fantasies of endless abandon." The speaker can't name the chemicals behind it, but knows exactly why it matters.
Then the mood turns. The speaker is older now, the nights are over, and the sharp details they once guarded "like diamonds" have blurred into "soft-edged memories." Freedom has been replaced by obligation, leaving a sense of distance and of being lost. The tone is wistful and a little weary.
The ending shifts again. Instead of settling into nostalgia, the speaker refuses to give up, admitting that hopes die but insisting we can bury them and begin again. The final lines, "just watch me," are defiant and blunt. The poem moves from soft longing to stubborn determination.
