There is a certain kind of modernist story that involves the sudden appearance of an inexplicable thing in an ordinary social situation -- something ususlly large and unavoidable -- that's not particualrly threatening but is inconvenient and eerie. Gradually people come to either accept it or explain it to themselves. Eventually it vanishes, or it never does. The only example I can think of is Marques's "A Very Old Man with Enormous Wings." I know there are others. ANy examples?

Stephen Vincent Benet's "The King of the Cats" may be an example of the type.
(It's a fantasy trope, isn't it? The Dragon Griaule is an example of this, and Towing Jehovah, on the monstrous side.)

Calvino's three Our Ancestors narratives mostly fit that template: Baron in the Trees, Nonexistent Knoght, Cloven Viscount. Smog and The Argentine Ant are about people needing to make environmental adjustments, but both are plausible. Some Cosmicomics tales involve sudden encroachments of a disturbing rather than threatening nature, e.g. The Daughters of the Moon.
And that science-ish essayist popular in the '70s, something Lewis or Lewis something, had a story about mutant fish in a city that everyone quickly got used to.
I forget how the populace reacts to discovering Uqbar in Borges' stories, other than being gradually contaminated by its ideas and impossibilities. Which is a kind of acceptance, I guess.
The Woody Allen segment of New York Cities involves a giant woman in the sky that everyone comes to take for granted.
How'd I forget such a Welsh-bomb of a name?
Woman in the Dunes? Hmm.
Can't remember if part of the point of The Exterminating Angel was that the horrible upper middle class people complained about their magical imprisonment but didn't have much curiosity about it. Or if they instead did and it was more about just deserts.
It is not material though.

In stories about elephants in the room, there is no thought that we should be sorry for them. Large, unavoidable, disliked, fading into wallpaper or sky, they are never seen as beings because their scale is not fathomable. If the Triffids of post-war Britain had stood still longer, we would have seen them as communication pylons and they could found a better moment.

2. The book with an infinite pages in Borges's The Book of Sand.
3. The "stepper" (an inexplicably simple device that helps people "step" from one Universe to another), or for that matter, the "Long Earth" itself, in Terry Pratchett and Stephen Baxter's The Long Earth.
4. Also, perhaps, the monoliths from 2001: A Space Odyssey?
