Meaning of "One Thing Left" by Richard Marx

"One Thing Left" by Richard Marx captures the internal conflict of someone who seems to have everything going for them, yet struggles to let go of a past relationship. The juxtaposition of the narrator's seemingly perfect life with the lingering pain of heartbreak emphasizes the complexity of human emotions. The lyrics highlight the idea that external success and internal healing are not always aligned. The repetition of closing doors, locking them tight, and turning off lights symbolizes shutting out the past and embracing new beginnings, but the unresolved feelings towards the person they're trying to get over continue to haunt them. The constant rain imagery amidst the sun's presence reflects the persistent sadness beneath the surface even during moments of happiness. Overall, the song explores the idea that sometimes, the hardest thing left to do is to move on from someone, even when everything else in life is going well.
