In theory, any situation, regardless of positivity or negativity, can be turned into a beneficial opportunity, to suit whatever need or intention there is in mind. To those who least expect it, it is called "subverting one's expectations."
Actually, I am unsure if there is a situation that cannot be subverted in any way. Not only a situation, but literally anything in existence, including concepts.
Have you ever seen a woman in a tuxedo? Whether or not you did, that's how expectations are subverted. You take something that is by tradition, a.k.a. expected, and use it in an expected way. In this example, the subversion is of good intention, probably.
Are you a woman who wishes to dress respectfully? You can wear a tuxedo and still appear respectable. As of today's standards, being a man and dressing respectfully like a woman might not, unfortunately, get the good-intended results you may have in mind...
Subversion is essentially this: undermining the foundation of something and taking the rug off its feet. Sometimes you will get the intended results, and sometimes you won't. As a result, the desired outcomes of your opportunity may also subvert you.
That's the problem that lies behind every expectation, dear readers. Every expectation is like "asking" yourself to be subverted by reality. When the philosopher Socrates, told us that he knew that he knew nothing, maybe he knew what he was talking about? Heh Heh.
It is a tool that is essential to the comedian. At one time, there was a scene between an Israeli children's comedian and a woman. It seems that the woman accidentally said that she had cancer.
Since in Hebrew, "cancer" also means "crab," the comedian subverted some children's expectations by referring to the "crab" as her pet. To further distract the audience, he also made up her "turtle" and "goldfish" pets.
So, as you have just witnessed, even the darkest of topics can be used to subvert grim reality by making us think positively, by using the same concepts.
As such, when I am reminded of that dastardly, goody-two-shoes woman who told me that exposing my emotions is a mistake (on Valentine's Day), I quickly remind myself that her name is also said as "Hen" in English and be glad that I don't eat her words, for I am a vegetarian.
And, as I previously stated, your actions can subvert yourself whether you intend to or not. In one scene of "The Great Mouse Detective" Ratigan the antagonist and his henchman, Fidget, fly away in their airship with a girl they kidnapped. Fidget loyally reported that the airship holds too much weight, so he advised getting rid of the girl.
The big rat, Ratigan, threw away his tiny henchman instead. What a way to go. Death by doing your job correctly, with his final wage being a penniless punchline.
Thus, for every optimistic philosophy of life, can we really say that subversion is unnecessary? After all, it has the power to destroy even the grimmest of insults and defeat the nastiest of trolls.
In the fictional song "Ash Ketchum VS Charles Darwin," Ash mocked Darwin for losing his three children because they "caught all" the fevers.
Darwin actually agreed with the boy, saying that it was indeed hard. And then replied,
"[It was] as hard as the **** that Oak gave your mother."
Wonderful, is it not? An... evolution of finishers.
