Remember folks, when a neurotypical person you’re working with asks “what time do you usually have lunch?” they mean they’re hungry and would like to stop for lunch very soon.
Or they have an errand to run.
What they don’t want to hear is “in a case like this I work through my typical lunch break and eat when I’m done. I think we’ll figure this out in 5 hours or less.”
And when they then say “oh, OK,” they don’t mean they’re OK with that, they mean you sound like you won’t accept their weakness and they don’t want to risk complaining.
