I agree with shay too... maybe it's said when you don't want to care... or wish you felt like you care... and since it's bothering you enough to post.. maybe you really DO care. IMO it's said sometimes when you care, but you're either trying not to, or unable to do anything about it so you try to tell yourself it doesn't matter anyway?

There are things we don't need to care about. i.e. something that's already done with and you can't change.

ME? Idon't care for most of those terms that couldn't possibly apply to me anyway... and "you're" going to call me what you want to anyway to my "face" or not.
