Here is one of the oddest things I have learned over the course of my life: people don’t believe you when you say you don’t care.
Of course, the main reason for that is that so many of them don’t mean it when they say it.
“I don’t care” is something many people say when they are feeling petulant and sulky, or hostile and rebellious, or when they have just had their feelings hurt and are longing to return the favor. It is often used as a substitute for “leave me alone” or “I’m hiding.”
Genuine indifference is generally frowned upon by society. So, if you happen to be one of those rare individuals who actually mean it when you say you don’t care, people either don’t believe you or they think you’re mad about something, which is the same as not believing you but in a more specified way.
See, the thing is, you’re not supposed to not care. You’re a human being, a social animal. You ought to care. You are hard-wired to care. Something is wrong with you if you don’t care. You. Must. Care.
