Bug: I couldn't care less
Just a bit off topic today, but this has been bugging me for years and years and I finally have a significant channel through which I can attempt to set the record straight.
I'd like to report a bug in English language culture.
Often times a co-worker, friend, or family member may approach you and explain a situation they are in, a situation that does not concern you what-so-ever. Normally you show interest, because you're nice like that. Good for you. But sometimes you simply aren't in the mood. There are many ways you can communicate this to your conversationist, some are polite white lies like "I'm sorry, can we talk about this another time, I am late for a dentist appointment." Some are trickery, like "Look! Over there! <runs away>"
But the best one by far if you are feeling particularly foul is the blunt exaggeration:
I couldn't care less.
This lets them know that the subject is so uninteresting to you, so unimportant, that you could not possibly care about it any less than you do, no matter how hard you may try. You have in fact reached absolute zero on the caring scale. Wow... that's cold man. Have you no compassion?
However... as is the case for many sarcastic remarks, the sayer does not always appreciate the meaning of what they are saying. They just say it because they've heard it, basically. There's nothing wrong with that. But if you're going to spout a phrase designed to strike your subject with pure and utter rejection, you best get it right!
The bug is that so often what people actually say is:
I could care less.
O RLY? So what you're saying is that there is still a detectable trace of care left in your heart. You care somewhat, therefore it's possible that you could care less about it. That gives me hope... heck, it's almost a way of urging your conversationist to continue! Yes, yes, please continue... I could care less about the subject, so perhaps you have hit upon a subject we can share together! Hooray!
It's more common than you think. I'm surely not the first to call this out as a common mistake. But clearly we as a people have not been doing enough about it. It's even crept its way into the lyrics of a hit song!
One more thing... if you find any grammatical or spelling errors in this article, just know this: I couldn't care less about them. :)
