In an attempt to start a totally pointless thread, I've always said "I couldn't care less", because I thought that meant that it was impossible for me to care less about the topic.
However, I hear a lot of people say "I could care less". I even heard it on a radio program yesterday.
If you could care less, then it means you do care a little. If you do care a little, then it's kind of an odd thing to say, isn't it? Well, I care about it a little, but not enough to talk more about, rather than I couldn't care less, which means I don't care at all.
So could you care less, or couldn't you care less? Which one is it?
