I have pretty much always been polite in a genuine, immediate way that takes people off guard. I don't tend to either notice or decide to recognise what counts as how nice you should be to someone you just met or what you should say. However, I also forget almost that it ever happened when they leave and most people don't know how to handle that kind of approach anyway. I have an Fe dom mother so I guess that accounts for some attention being paid to Fe. I mean, I'd be nice, but I wouldn't go out of my way to make friends. I was voluntarily, naively, happily alone 98% of my time or talking with my one best friend or the staff. That's pretty much how things are now, except I am much more socially-aware. My primary school class never changed so by the time I went to secondary school I had no idea how to make friends. I'm still terrible at it. So, that's my Fe social skills snapshot over 18 years. The difference now is that I consciously choose to avoid people and how I act towards them based on my routines, experience and principles.
I have a different take on your clothing point. I recognised clothing conventions, but after deciding girls' clothes were illogical I have gone out of my way to wear at first clothes I thought were practical and then clothes that were both practical and projected the don't-judge-me-by-your-girl-stereotypes image I want. At the moment I do that and just wear clothes I think are oversized, warm, durable and comfy. So I wear jeans absolutely everyday, plus a hoody or fleece and t shirt. There is a subconscious recognition of social patterns, but my parents, again, were an Fe-Si and an Si-Te so I might be slightly more affected than nbrmal. This does not mean I go along with convention. I avoid it. I was also an extremely naïve person until about my mid-teens. I see these things as having subconscious effects on how I think, but not what I choose or my morals, values and personal image.
Regarding emotions, dealing with either my emotions or those of others just was not part of my life when I was younger. I didn't think about it and I may well not have been aware of it. Learning to deal with emotions, in a dispassionate, controlling Ti mind, has been and is difficult.
That's about it, I think.
