Songfacts®:

• "23" finds Noah Kahan wrestling with one of the most painful realities in any long-term relationship: loving someone whose self-destructive habits keep placing them just out of reach. The song works both as the story of a romantic relationship strained by addiction, and a portrait of a sibling or lifelong friend whose substance use has slowly eroded a once-unshakable bond. Kahan never pins down the relationship, and the details are specific enough to feel lived-in yet broad enough to encompass anyone who has watched a loved one disappear in stages.
• Though emotionally exhausted, Kahan remains deeply invested in this person trapped in a cycle of relapse, recovery, and disappointment. That dynamic reaches its emotional peak in the line, "I hope you stay gone." On paper, it reads like a rejection. In practice, it's something sadder and more complicated. Kahan isn't wishing for permanent absence so much as wishing to preserve the version of this person he still loves. If they stay away, that memory remains intact. If they come back unchanged, the cycle begins again.
• "23" appears on Kahan's fourth album, The Great Divide, and is one of five songs he wrote entirely on his own, alongside "Orbiter," "Headed North," "Spoiled," and "All Them Horses."
  
  The absence of co-writers gives the song an unusually intimate quality. Every observation, every contradiction, and every unresolved feeling belong solely to Kahan.
• Twenty-three, clean in the engine heat Teaching me how the thing runs
  
  The image recalls two people leaning over a car engine, sharing knowledge and companionship before addiction complicated things. Anyone who has worked on a car knows the peculiar warmth that rises from the engine bay and settles across your face. In Kahan's hands, that heat becomes a symbol of intimacy, a language spoken through shared experiences rather than conversations.
  
  Cars are a recurring motif across The Great Divide - from the American car he drives to his sister to the dashboard devil - but here they represent something more personal: a time before the fracture, when the relationship had a language that didn't require words.
• Tattooed your initials into my right arm
  So I'd see your name when I lift up a drink
  
  What begins as an act of devotion becomes something far more complicated. The tattoo ensures that this person remains present during moments of weakness. The lyric also draws an uncomfortable parallel between Kahan's own drinking and the other person's addiction. They may be fighting different battles, but they're carrying each other into them.
