My Fe issues as a kid were usually due to my behaviour, mainly not taking other people into account when I wanted something; or if I did take them into account, I still expected people to do some things for me that I thought was pretty reasonable (logically reasonable too). Also because of the insensitive jokes I made (verbal or physical jokes). Sometimes physical fights as well. Overall I was completely unaware of Fe things. It would not at all register or register only unconsciously 99% of the time if people had a problem with my stuff, how people viewed me, etc. I recall a case where it was conscious temporarily but meh.. I forgot that fast though I'm pretty sure it still affected me unconsciously. Basically, I would be pretty hostile in my attitude to most other kids and I saw that as natural. Idk but some of this might be enneagram too...
The car example, I suppose people ask about feelings when they ask "how are you" when you are physically unhurt. I might not explicitly ask how the person is but I would probably make some facial expression half consciously.
I don't really ask others if my behaviour was/is okay.. I can obsess over it a bit at times but I don't usually ask others about it. So it usually stays unresolved. Yes, I can sometimes get worried about how others see me but I'm usually not thinking of this and I'm definitely better off not worrying about this. I feel more like myself that way.
You've just displayed some Fe hereIs it messed up we're talking about me so much in Zombie Killer's thread? Perhaps we should move this discussion to another thread.
Though, if ESTP means I must be "ridiculously negative and pessimistic about the future" then I'm no ESTP I usually don't think a lot about the future. Or if I do think something negative, I rarely express it.
Anyway, the difference for me is that the inferior Fe thingies are more common and I'm pretty used to it so it's no big deal I guess . Well it's annoying and shit, sure. The inferior Ni thingies are much harder to deal with but that stuff happened only like a couple of times in my life. It was extremely bad until I learned to gain some control over it. Otherwise, I certainly don't relate to habitually fucking up interpretation of shit through negative Ni. Well, or maybe I do get little irrational worries about the future more regularly than that but it's a lot more vague than the examples given and I have an outlet for such stress that works fine and so I don't even notice most of the time. (This isn't the same as the other control thingie that I talked about above. The control over the bigger Ni related issues is more volatile.) The Fe problems I certainly notice much more and I don't have any nice method for fixing the Fe-related stress. Sorry if this didn't make much sense, I'm not being very concrete here I know.
Overall, the small Ni things are easily controlled. The big ones are not easily controlled, achieving control over it seemed entirely hopeless sometimes & usually made worse by Fe acting up as well. The Fe things - without Ni - are not really controlled, at all. I still conclude ISTP from this but...
