I watch this Zoe bee video a little over a month ago. Talking about how we use metaphors to grasp abstract concepts, how we use it in our daily life and how we use as map, in our politics and so on. Something imo she didn’t focus enough is the metaphor we forget were ever metaphors(fun fact: the word “metaphor” has the world “meta”). This use one here, its like the three fishes with water. You see it so much you forgot it ever existed.
not exactly what you asked, but most people get “blood is thicker than water” wrong. It’s actually “blood of the covenant is thicker than water of the womb” which means it’s the exact opposite of what people think it means.
That origin is apocryphal, and likely based on a misunderstanding of a text that simply used the original phrase
