Inwardly, I assume it's unfocussed thoughts appearing at random based on what you see, hear, and do. Mum seems to do this, and may honestly be NeFi/FiNe. The behavior I have seen is magical thinking. That's basically it, and that sounds about right for ENFp/INFj. However, it could also be Si/Fe, which makes sense, as she takes very good care of herself. However, I don't think she notices how well she takes care of herself relative to the rest of the population, which would imply Fi/Ne, and we've come to work quite well with each other. Se POLR sounds like that kind of accidental ignorance which I know her for. So. She's a wizard.

I mean like she'll stumble into crud that benefits her accidentally. Things will accidentally break for the same reason, for example she has a habit of crashing on the bike
This worries me, but she'll be fine.
