The speaker asks one anxious question over and over: when I'm gone, will you miss me? It opens and closes the poem, so the worry hangs over everything in between. What gives it sting is the list of things the speaker fears being compared to: leaves stepped on last fall, food thrown out, papers recycled, friends who drifted away. These are ordinary, disposable things, and the line about friends "who knows where they are now" shows how easily people slip out of a life without anyone noticing.
In the middle, the speaker turns generous. They say they will miss the other person, even imagining them on a bus, heading somewhere to build a new home. But that kindness comes with a doubt: "will you do the same for me?" The mood is wistful, a little insecure, and quietly vulnerable. The plain, spoken language makes it feel like a worry said aloud rather than a polished speech.
