Prev tags for posterity. And now to the OP. Please understand I am using the hypothetical, generic "you", not talking about you personally but about the attitudes that I have to deal with. I don't know whether you are neurodivergent, or your exact situation, just giving some perspective because I know that many, many neurotypical people believe the same things.
Small talk about the weather isn't about the weather. It's about how nice it is to be around the people you're talking to,
Is it nice, though? Like, I get that this is the purpose of small talk, and sometimes I'm happy to engage in it. I don't speak for all autistic people (and we should be careful to avoid conflating all neurodivergence with autism) but the problem for me is that a significant portion of the small talk I have to engage in is either entirely for the benefit of a neurotypical person because Having A Conversation makes them feel good, but for me it's work, or neither party in the interaction actually wants to be around the other and have a conversation but we are mutually required by social convention to pretend to enjoy it even if it makes the interaction take longer.
The problem is that it is not nice to be around you if you try to force a "human connection" that is not pleasant for me, that actively drains my energy, and you either ignore my signals of discomfort or notice that I'm uncomfortable with this interaction but decide that what would really make me feel better is you asking me what I do on the weekends, and I hate that I am then obligated to either perform fake enjoyment of this or risk you getting offended if I tell you you're making things harder for me.
You know what else is often a "yes we're both present and being people together, it's nice being around you" gesture? Smiling. But, we've all seen the articles pointing out how obnoxious it is for women especially to get told to smile by random strangers or acquaintances, that it's infuriating when someone feels entitled to tell someone to perform emotional labor for them, and that sometimes you don't feel safe saying no because there's a risk of them becoming hostile if you refuse? That's how the cultural expectations around a lot of these rituals feel.
(and yes, I am aware strangers trying to make small talk in inappropriate environments is annoying to many/most NT people as well)
Also yeah, like the previous reblog said, it's not like as an autistic person you can generally expect the effort you put into participating in social rituals that feel good to neurotypical people to make others happy to be reciprocated. Like, making small talk about the weather or some other random bullshit as a way to feel connected to the person you're talking to is not inherently different from trying to connect to someone by infodumping, but those aren't treated the same way.
or just saying that you're both present and people and you're being people together...
...It's like looking in a mirror and not seeing your reflection.
And this is the other crux of the problem. I don't think NT people consciously, intentionally do this, but how it feels in practice is that rituals like small talk are a shibboleth, a test of whether you're "being a person" correctly that I can be ostracized for failing, and in practice the cumulative effect of all these little rituals is weeding out neurodivergent people who don't have the skill or the energy to mask well enough (and these can also suck for people trying to navigate cultures that have different standards of etiquette for how to handle these interactions, as I think some of the notes have mentioned).
This is what I mean when I say so many of these rituals are fake bullshit: yes it's real communication, but you're asking questions you don't actually want an answer to and really it's a test of whether I'll tell you what you want to hear. That metaphor was really apt: you don't want to see me, you want to see your reflection, and when you don't see it, you stop seeing me as a person.
And not only is this language bordering on dehumanizing, but with all due respect: the fact that neurotypicals can complain about this with a straight face is a textbook example of abled people seeing it as a profound injustice that they have to occasionally briefly experience a disabled person's daily reality. Forgive me if I'm not sympathetic to your discomfort at having to interact with people whose natural way of communicating is foreign, difficult, and maybe a little unnerving: how the fuck do you think we feel? I do not have the privilege of being able to feel entitled to "see my reflection" in every person I interact with, and yes I have gotten used to understanding or at least being able to bullshit my way through neurotypical social conventions (both because of volume of interactions and because I am forced to to survive), but still: I have to live with this all the time, and society expects me to not only just shut up and deal with it but to devote a large amount of my mental resources to shielding you from having to experience it once, because society values your discomfort over mine.
Let's put it another way. Imagine if many aspects of your daily life that are necessary for survival required you to use a computer system that demanded a capcha response at random intervals to do just about anything. And it's often pain in the ass capchas, like word ones where the letters are so distorted it's hard to tell what they are without squinting at them for a while, or "select the squares with cars in them" ones where there are tons of squares with just a sliver and you have to guess if it wants you to count those or not. Sometimes you get a blue or gold dress puzzle. Sometimes you solve it correctly but the algorithm decides to fail you anyway because it decides the way you move your mouse is too robotic.
You have been locked out of accounts for failing these before. You have had job applications rejected because the capcha you had to solve before the interview thought you were a spambot, and didn't even tell you you failed until after the fact. Even if you get really good at consistently solving capchas, it would still be a pain in the ass. Now imagine most of the world doesn't see why this is a problem for you, and when you complain about it they just tell you the purpose of capchas and give you tips on how to solve them better.
