Yeah, the whole way it works is fascinating. Having exec dysfunction – as Brian does – just a fact with ADHD but other things too – I think you have a thing that messes with yours you were talking about? – anyway, having exec function malfunctiong messes with “timing” of common everyday things.
Personally I think people with exec dysfunction can sometimes be drawn to writing for communication because one gets more control over production and it lacks the pressure you get from face-to-face communication that requires comprehension and response within a very short amount of time.
