Yes we understand that but the point is that ND folks don't automatically know which version is appropriate. Our brains tend to go through an algorithm manually each time, where NT people are much more automatic like you're suggesting. It's like if someone with executive function issues like in ADHD and autism told you they struggle to remember things and you tell them to "Just write it down" or "just put it in a calendar 😀" as if this is some kind of new trick they haven't thought of. This is one of hundreds of daily examples where ND people have to manually go through the mental list of appropriate social protocol that for NT is just somehow magically instinctual.
The point of this post is to highlight one of the many ways that things are more difficult, challenging, exhausting, annoying, frustrating for ND people. This post was made in the autism community to commiserate with other ND people and discuss amongst ourselves, not to educate NT people.
But since I am procrastinating at work and have the spoons, I'll take a stab at helping you understand. But I would appreciate if you would recognize the imposition you make coming in asking to be educated.
Imagine if for every thing you did all day you couldn't remember how to do it or even what to do when and instead had to manually pull up a check list of steps to take to accomplish that thing, but also the pencil you used to write the list has been smudged so you can't really read everything on the list, and when you wrote the list you misunderstood the instructions so the check list is unreliably correct. And the check list has sub points so if this then that, else this other thing. So every thing you need to do every day of your life instead of being automatically pulled up subconsciously by your brain and just done, you had to go through this list and figure out each step new each time.
For ND people, to varying extents, this is how we live for real. And it adds up in impact, but we don't get a break. And when you're already overwhelmed and exhausted, each time you have to pull up the checklist and figure out what to do you get worse at it. And it's stressful and embarrassing to have to check the list each time, especially because often times you mess it up because you can't read every line clearly or you wrote it down wrong last time.
There's no solution, there's no tips or tricks to help. There's no medication to fix this problem or skills we can learn to make this problem go away. It's how our brains are wired. We would rather live differently. But we live in societies that have chosen not to educate themselves about different neurotypes and refuse to accommodate any differences.
Instead the "weird" guy at work who is too quiet but then goes off on a coworker because they didn't follow some stated rule off the workplace, that everyone knows don't actually matter even though it's never been said out loud, and why does he have such a stick up his ass, what a loser let's be mean to him now because he's obviously not deserving of our understanding or respect for being such a weirdo.
Or that coworker who wears headphones at her desk and is always calling out sick from work. I heard she asked to work from home, who does she think she is? how lazy can you get amirite? Something about being distracted by noise and The overhead lighting, she needs to suck it up! We all get by just fine, why can't she? And we like chatting with each other over the cubicle walls, she needs to loosen up.
