Honestly sometimes with all these relationship troubles I'm actually honestly tempted to break up with my boyfriends just to prove to people that you don't need other people to be happy.
But that might be a douchey thing to say...
You could think about what you're planning more. Like, how are they connected and
why you're doing it like that for this "point". Because yeah, that is pretty much a dumb thing to do to 'prove that "point"'.
When just being sincere is a point in itself in the first place.
It shows, even if you don't tell it. People can see these things by behavior and communication.
And if there's any doubt in whether people believe the idea--there's
ALWAYS one person in common: Yourself. You are the common variable in all these proving times.
Please be specific rather than generalize 'people'; it'll mess up what you're really aiming for.
You don't need to do these things to 'prove' something, especially if this 'something' is an oft misattributed quote out of context about an abstract idea, that you're against anyway.
Get to know people more. You'll discover that being happy and being connected with other people are related. But also that happiness, or the origin of happiness, is also importantly present with the concepts YOU work with.
Though I miss if that's merely speculative posting in public. :v Because my first impression was that you were saying that in such a way to show the absurdity of the idea...until I read the second paragraph and then the meaning changed into "Is Cinder seriously being serious about actually possibly doing that?" rather than "That's one way to show the idea, illustrating an extreme example..."
