I have ADHD myself so I can relate, but this is something you can get better at with practice. I sometimes find it tedious to wait on other people when they seem about to say something very obvious (especially in an argument), but cultivating patience ultimately makes for less stress.
I am getting better at it, and I am trying. It's the potential framing of this as a character trait worth scoffing at I wanted to push back against. Even though it is a learned skill for a lot of people in practice, and some are genuinely fighting an uphill battle there.
Friends and family know this about me (more or less), so they treat it as what it is: an attempt to collaborate to reach a shared understanding.
With strangers and acquaintances, I know this can be irritating so I curb it at the expense of possibly zoning out.
I mention all this to offset the following assumption:
> A lot of people don't have the patience to unspool a thought or the instinct to ask a clarifying question instead of plowing ahead with their mistaken assumption.
It's not for a lack of patience or instinct or intelligence or <insert virtue or character trait of choice here>. Some of us find it genuinely hard to keep lots of context in working memory (due to a working memory deficit), without taking an active part in whatever demands it. And it's not for lack of trying.
