When I say "I couldn't care less," that is what I mean.
100% totaly do not care.
Others say " I could care less," which I find a little ambiguous.
If you "could care less," how much more could you care less?
If not caring at all is 100%, it would be more definite if you gave how much you "could care less" as a percentage, then we could quickly work out how far from "couldn't care less, your not caring is."
Now "I couldn't care less," how much more or less you "could care less," but please let me know how much you could care in the beginning, so I know how strongly you feel about caring less over all!
Thank you
