Hi. IDK if you were being somewhat sarcastic or if my humor was missed without the necessary emojis. I enjoy Ne-Ne bonding in social/platonic situations. Like EIIs (and ENxps), LIIs can be very goofy. Meeting another Ne ego is always interesting. Of course, there are the philosophical discussions, but there's also a similar sense of humor.
I don't think EIIs are dumb at all. Honestly, I wish my Fi could be upgraded. It needs some work. The fact that EIIs (and other Fi egos) have Fi clarity and maneuverability is pretty awesome from my perspective.
