semantics tip

the phrase "i could care less" actually means that you DO care.  look at it another way.  if i were to say, "i could drink less," it implies that i drink something, but if i wanted to, i could drink a little less.  if you DON'T care, you should say, "i COULDN'T care less."  it means that the amount of care you have for whatever you're talking about is zero.
