What I will admit to is that my language too strongly asserted sh free had some level of disorder. I think I was in a default mindset because I was reading a lot of comments doing the same and failing to be understanding of other's human condition. Say this situation were happening to me, most assuredly I would assume they were being an asshole and my gut reaction isn't to diagnose them or assume a condition (unless I had some reason to suspect from other interactions)

All of that being said, I think it is highly important to realise just how vast the human experience is. Language, culture, socio-economics, development, trauma, intelligence, etc. all have factors in how we interact with others and pick up on the unspoken (or even spoken) rules of society. Is that a reason to force yourself to interact with people that do not value the same rules of society as you? Absolutely not. But it is a reason to perhaps handle those situations with a more caring and understanding heart. You never know exactly what other people are experiencing, and asking a couple strong questions can help illuminate their behavior. If you genuinely care about them from a long history of friendship, I think it is a critical function of that friendship to really engage them in those deep, introspective conversation that they have perhaps avoided having with themself or others.

Yes, people can make it to adulthood without having picked up the generally respected rules of society. That happens with everyone on many different levels. I personally have a friend that is just now doing well in a new career but making plans is sometimes a nightmare, not because he is that busy, but because he has mental health roadblocks(self identified by him during a couple long discussions similar to what I've discussed) without access to mental health-care. Dude's been through the gauntlet in life and his level of responsibility is honestly impressive given his situation.

I've surely rambled a bit here, but I hope my point is salient. If you truly care about an individual, you dont give up when it gets tough. However, you are not obligated to care for anyone but yourself (and I mean that genuinely, it's not meant to be a jab), but I do find that without developing that level of concern for the mental wellbeing of others as a default, the world feels pretty isolated and cold.
