One great habit to get into is when you have something like this that can be mistaken for something rude you can just preemptively apologize for it. “I’m neurodivergent and have a tendency to overexplain” doesn’t make it not frustrating but it does make me not think you’re assuming I know fuck all. I also like using “I don’t know how much you know about x” it makes it very clear I understand you may be more knowledgeable than me on this
