I'm a different person than the one you've responded to, but I've actually been accused.

I am into weird shit and have ADHD like a bitch so I will often excitedly talk about my interests, or a story involving them, which are sometimes fairly niche and I know I need to explain whatever I am saying to whoever I'm talking to, because I know they don't know the ins and outs of X. I had an ex accuse me of mansplaining and said she'd prefer if I wait for her to ask before I explain something. Alright, fair enough, I mean I'd say I'm ADHDsplaining because I enjoy our conversations but I can work on that. So I complied with her request, a couple months go by, and she tells me I she hates the way I just assume she knows everything and will just breeze past terms like Castle Nut and Endplate without explaining them. She then didn't like when I explained that she asked me to do literally exactly that in very gendered terms.

I guess I'm just too neurodivergent for all this "other people" business.
