A Lesson Learned Too Well

Go To

"We should be careful to get out of an experience only the wisdom that is in it - and stop there; lest we be like the cat that sits down on a hot stove-lid. She will never sit down on a hot stove-lid again - and that is well; but also she will never sit down on a cold one anymore."

A person is taught a lesson and takes it to heart very well—too well, as it turns out. There are two variants (which by no means exclude the other):


  1. The person takes it to heart so well that the lesson is applied even to his or her own detriment (even the teacher may notice).
  2. The person applies the lesson to the teacher's detriment.

This trope can even go into Gone Horribly Right territory.

This can result from a few things:

  1. Accidental Aesop—there was An Aesop being taught, but the recipient learned the wrong one.
  2. The recipient learned the intended message, but it was the teachers who didn't think about the Aesop enough.
  3. The recipient disagrees with the Aesop and through its application, Shoots The Message.

  • In One Piece, the chivalrous "Red Leg" Zeff passed on his firm belief in never striking women to his protege, Sanji.

Even Nami, Sanji's female crew-mate, has declared Sanji's intentions admirable but his execution idiotic.

  • In the lore of Battletech, The Clans settled a cluster of planets that were inhospitable to life and extremely resource-poor: As a result, they designed their society entirely around maximum efficiency and minimal waste. This included all forms of warfare and conflict, which essentially became a system of Combat by Champion backed by a Proud Warrior Race Guy Code of Honor that minimized the amount of personnel and materiel needed to solve a conflict and bound all participants to the outcome no matter their feelings on the matter. While this system allowed Clan society to thrive for centuries, it proved fatal when they attempted to invade the Inner Sphere: While inferior in technology and skill, the Inner Sphere could afford to think beyond the scope of individual battles and eventually ground The Clans to a halt on the operational level.
