Maybe Not

Something that sorta bothers me is when people say "I could care less if..." That doesn't make any sense. It should be "I couldn't care less." If you could care less, that means that you at least care somewhat, and can give up some caring. If you couln't care less, that means that you don't care at all. There isn't one bit of caring that you could give up--you couldn't care less, because there isn't any caring to being with. Do you care?
