The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at and repair.
I want to suggest a feeling. It's ridiculous to assume you can state an opinion. Somebody else can never relate to the lyric in the same way because their whole experience is different. You can only suggest, then people add their own history and experience to the lyrics.
