Saying “I don’t care any more” usually means you still do.
In some cases, you even struggle for the opportunities to say it.
But the subtlety of the notion lies in what would happen, embarrassingly, afterwards — the listener, who’s supposed to care, usually stops to do so.
Let’s see what happens between the embarrassor Nathan and his listener girlfriend Sylvia.
“Why? Why you didn’t listen to me? If you just did it as I told you, my father wouldn’t…”
“My gosh, Syl! I couldn’t fake it! I just couldn’t! Why do we have to fake things to be together?”
“Because that’s the only way to make us possible, Nathan! Think about what you’ve done! Think about it! Now you’re making me choose between you and my father!”
“I’m not, Syl! That’s not the point…”
“You’re not listening! Can’t you see the point? I can’t choose you over my father…”
“Or vise versa!”
“What do you want me to do now? What am I gonna do?”
(Ten more minutes of fight later.)
“You know what, Syl. I don’t care! I don’t care anymore!”
