In my perspective..

If you really "didn't give a fuck", you wouldn't say "I don't give a fuck" because when you say "I don't give a fuck" it's like you're hiding the true fact that you do "give a fuck". So in fact when I hear you say "I don't give a fuck", I hear your heart whispering..."Shit man I really do give a fuck cause I'm afraid of what people might think of me. Cause in all honesty the littlest things bother me, so to keep me from breaking down and showing my true emotions about it, I say "I don't give a fuck" to keep myself in denial".
