Bingley and I just did the Myers Briggs personality test (why I tested him I don't know, as he's the clearest INTJ I know) and I'm INFJ.
It's an interesting combination. Two extraordinarily introverted and high achieving individuals with aspirational goals dealing with minutiae that stresses them out.
Sometimes it's very very hard. But on the plus side, being so very very similar, we understand each other well.
