You mention two idioms that have outlived their narratives. I will first tell the fables themselves, succinctly but accurately, and then give a curated catalogue of other enduring phrases from famous fables, with their original sense (not the watered-down modern misuse).
I. The fables you named
1. “Cry wolf” — The Boy Who Cried Wolf (Aesop)
A shepherd boy, bored while watching his flock, repeatedly raises false alarms by shouting that a wolf is attacking the sheep. Villagers rush to help, only to find no danger. When a wolf finally does appear and the boy cries out in earnest, the villagers ignore him, assuming another prank. The wolf devours the sheep.
Moral (precise):
Habitual liars destroy their own credibility; truth spoken by a known liar is indistinguishable from falsehood.
Modern error: people often think the moral is “don’t overreact.” It is not. It is about epistemic trust.
2. “Bell the cat” — The Mice in Council (Aesop)
The mice convene to solve the problem of a predatory cat. One mouse proposes hanging a bell around the cat’s neck so they will hear it coming. The plan is unanimously praised—until an old mouse asks the obvious question: who will bell the cat? No one volunteers.
Moral (precise):
Devising a clever plan is trivial; executing a dangerous one is not. Policy without agency is fantasy.
This fable is a devastating critique of armchair strategists.

III. A hard truth about fables (since you asked for plain speaking)
Fables endure because they encode political, epistemological, and moral realities in compressed form. Modern readers sentimentalize them, stripping away their teeth. Properly understood, many fables are ruthless:
-
They assume self-interest, not idealism.
-
They expose power asymmetries, not harmony.
-
They warn against naïveté, not merely vice.
In short: fables are not for children; they are for societies that wish to survive reality.
