How often have you read or heard something like "I could care less how many people..."? What they are trying to say is they don't care, not even a little bit. But if you think about it, if you could care less, that means you do care.
What is meant is "I couldn't care less..." This implies that you don't care at all.
If I say I could care less if anyone learns anything from this blog, that's true, but an understatement. I care very much!
But I couldn't care less about the winter temperatures here in northern Minnesota -- at least now that we're close enough to spring that they shouldn't dip into the -20's again. I dress warmly and prepare for cold weather. I do, however, mind the snow!
