Downside of hyperfocus on a subject...Casual or unintentionally careless treatment of the favoured medium can result in a loss of patience with others. The mindset is a naturally occuring phenomenon, a self applied discipline akin to those of professional athletes. It is something you know inside and out. You are more than a dabbler, it is an escape. The patterns, the rhythms and rhymes...It doesn't matter to the majority of people nor should it, but it occasionally someone takes a bat to the patterns.
Internally you are screaming, frustrated by what could have been circumnavigated by five minutes of reading and basic research. At the same time you are highly aware of the amount of effort that has gone into your own work. You sit there wondering, why not take five minutes in the first place? You should be nice and kind and polite, but you're at the point where you have to be honest because the subject matters. It deserves more than a shrug. A stupid way to look at things, undoubtedly, but that is precisely how my brain is wired.
Similar case in point: First day of kindergarten a teacher took the book I was reading before class away. I asked her why she was taking it, her response. 'Because you don't know how to read a book that big.' It was Ozma of Oz. And having finished the prior books in the series over the summer my grandma had given me the book so I could continue with the story. I asked the teacher to open to a page and see if I could read it to prove my point. She opened to the chapter Purple, Green, and Gold...I got my book back. Just like Billina freed everyone from the Gnome King. Challenging authority wasn't the polite thing to do, but I knew I could read and comprehend my book.
