Well, I am either an INFP with really good social skills, or I am an ENFP that needs tremendous alone time. I like both groups and seem to get along with both just awesomely, however, ENFP's can get on my nerves at times. The things that bug me out about the ENFP's I've been friends with is that while they are on the same page intellectually, and we can bounce Ne forever.. they seem to be a bit shallow. They share many of the same opinions and interests, but they always come at it from more of an intellectual, detached angle (Head type 6w7 or 7w6) and they sometimes seem very afraid of dark emotions and recognizing any dark qualities in themselves, which makes me feel that at times they greatly lack self-awareness. The other thing is that dom Ne's can go bat-shit crazy with assumptins at times. They just ne it to death without ever leaning heavily on fi and saying... okay, is this TRUE though? Does it feel right? So It's not unusual for me to watch an ENFP make great errors of jugement, especially in others intentions and charactor.. which is a bit baffling because I know they can have profound insight into others motivations.
As far as INFP's go.. I sometimes feel that they are a little too sensitive and un communicative. This REALLY sucks because I can at times be very crass in my behaviors without thinking to hold it back, and unintentionally hurt their feelers. I don't WANT to do this, but then they doorslam and I don't get the opportunity to catch it right in that moment and resolve it. So with INFP's I sometimes feel alot of unnecessary bullshit going on. But I still LOVE INFP's, and actually prefer conversations with them over ENFP's because of that dom FI.. they have highly weighed the value of their ideas, and when they talk about an idea it's not typically fluff.. they have pondered this for some time, and their ideas are often spot on.
