Because you can't just walk through life like a robot and expect to be a well received member of society... that's not how the world works.
I naturally just adapt and mimic what others do and how they act. To a degree. I still retain my sense of self, but any self I portray, depending on the group, can change and be tweaked still. It is something subconscious so things go more smoothly and I "emotionally" appear to fit in. It's a chameleon effect common with xNTP's and extroverted types is it not? Why do any of us use that mechanism? I would think it is there for a reason and like I said I'm not even that aware of it anymore.
Reading about it somewhere someone called it a "subconscious defense mechanism". Which makes sense. It just naturally happens with the flow. Only time I don't need to do this is around someone I am truly fully comfortable with.
Just "be conscious they exist"? I can't even tell what it is in the rare times I feel emotion often. I analyze them like a strange entity. But in some ways (like connections to others) I do fear them, because of the vulnerability such connections can present. I'm aware some sort of emotions exist within me but most times I rarely feel them much, or if I do they are very fleeting. Same with connections to people, usually either easily forgettable and shallow, or overwhelming which makes me freaked out.
Irony though since once I feel a lot I end up showing nothing and locking up.
My best friend is an INTP and I love him. Well he loves me too, if not ...he would have already get a good kick in his introvert ass (actually , I forgot how an introvert ass looks like
) !
He was thinking he has no emotions. Which is just detachment. He told me I am the only one with who he feels he is allowed to be himself (that is the best compliment someone can share to me).
We went together to an enneagramm course and believe me he could learn much more about how he really is.
He is able to use Fe at work. I can't ! I don't want my gosh ! But I am a night bird, I know owls and bats are not admitted in daily society.
I'm not an INTP or an introvert and I'm not dominantly a thinker because I trust my guts first of all, but believe me it takes time to trust one's emotions.
Everybody is different, I know. But to grow up one needs to meet great people, sometimes some challenges, or some revealing books.
As for your connection with people, I don't have any lesson to give of course as I rather consider myself as an endless learner, I had to solve problems within my family first
because I suddenly realised much later I was projecting things on people. Those are frequent in most people and unconscious (we're used to live with them).
Irony though since once I feel a lot I end up showing nothing and locking up.
That's typically and INTP problem. Word by word my best friend could have written down exactly the same words. He is one of the deepest person I've ever met on that earth...
I have advised him meditation, and took care to explain him in a rational way how a daily meditation changes our brain and improves our way of thinking (it is scientifically proven).
The problem with mental types being afraid is that you often use your brain in the wrong way, like everybody does
Then, you can conclude you are just totally normal :hi:
(not that I intend to) and I often intimidate as well with my glance.
