P&M VI - I Don't Care

There are some phrases that mean one thing when they are said in sentences and another when they are used as a complete sentence. Of course, when my friends say, "I don't care if I never see you again" they are merely joking. (What do you mean you are not joking? Maybe you are not but I am talking about my friends) but in the normal course, when someone says "I don't care if....", he actually means that he does not care.
But what if someone just says, "I don't care"? When this phrase is used as a complete communication, it very seldom means what it says. It may mean, "I don't care to discuss the matter" or "I don't care to let people know how much I care" BUT it, almost invariably, does not mean that you do not care about the matter.
"I am sorry you did not get selected"
"I DON'T CARE"
Now, that was loud enough to let the other person know how little you cared about the matter. How utterly indifferent you were about getting selected. Yes, we know.
"I am sorry she did not accept your proposal"
"I DON'T CARE"
 The entire hostel knows how totally indifferent you are to the girl's charms and how carefree her turning down of your proposal left you. They all know you are going to paint the town red celebrating your joy.
"I am sorry you lost your job"
"I DON'T CARE"  The entire city knows how much you care..umm, don't care about losing your job. Everyone and his aunt knew how little you cared for it and how much you were hungering to be free to do your own thing.
If you are sorely tempted to write something negative in the comments please understand that
"I DON'T CARE"
You hear me? I just don't care.
