The speaker seems to be at the end of something. The first lines read like a final tally: the "only sugar" is used up, and what remains is "only me." The sweetness is gone, and so is any company or comfort beyond the speaker alone. From there the poem turns to movement. "We" go looking for a home, and the odd phrase "like the best spoil" makes the search sound like a hunt for treasure, as if a home were something to be seized. The walk into the city is meant to bring change, so the title's idea of reinvention becomes a hope of starting over.
The ending shifts the tone. The speaker says they are "ashamed to have seen / a common town." It's unclear whether the shame comes from looking down on ordinary places or from having been somewhere so plain. Either way, the mood is uneasy: hopeful and hungry on the surface, with embarrassment and a little self-doubt underneath. The poem leaves that feeling unresolved.
