This is a translator's forum and we are striving to speak correct English and Spanish so just to correct a slight error for those who might be confused by the usage of the phrase
"I could not care less" versus
"I could care less":
The phrase
"I could care less" is an incorrect way to say that you could not be less concerned about something. It means you actually could be less concerned when you are trying to say you could NOT.
To put it another way:
"I could not care less" is the correct way to say you have reached the limits of not caring.
"I could care less" means, yes, you still care, at least somewhat.
This is a common mistake in using this phrase.
Think about it.
