Sarah's poem is about being asked to stay by someone who might leave anyway. The speaker has kept their promise and says they meant it, even wanting to stay. But the poem turns on a fear: that the person who demanded loyalty will walk away "like everyone else," leaving the speaker alone.
The feeling here is a mix of devotion, dread, and anger. The line about a "soul who's slowly rotting away" is the most striking image. It suggests the speaker doesn't just expect sadness but a long, quiet decay, as if they depend on this person to stay whole. The final lines shift the tone. Calling the other person "hypocritical" lets the hurt turn into accusation, since the promise only ever bound one of them.
The mood is raw and vulnerable, with the short, plain lines sounding almost like a confession. The title, "everyone leaves," hangs over everything and makes the speaker's fear feel like something they have learned from experience, though the poem doesn't say how.
