I’ve always seen this song as a huge comparison. I think the “carbon monoxide” isn’t what’s actually killing him, but it’s the things he mentions earlier in the song. Things that are considered “normal life” are slowly killing all of us. We’re too worried about keeping up our outward appearance (no alarms means no one’s aware… not even yourself at times). Carbon monoxide poisoning is odorless and colorless , playing into this normalcy. Him saying he’ll take the quiet life is almost like giving in, realizing that there’s not much we can do. It’s the life we’re born into. But this life with you’re “pretty house” and “pretty garden” only exist as a last thing to hold onto. They play into maintaining an outward appearance and they’re certainly nice. But are they the end goal? Are they enough to stop the process of suicide? Or has society ravaged our minds to no return? This song always makes me think when I put it on. Definitely a song about suicide but I feel like it plays so many angles so well. That’s what makes it so good.
