I think the intellectual conversations span 2 different sides of things. I see an ENFJ thinking an ENFP comes across as ditsy which would put a bad image in the mind of an ENFJ. Its the playfulness. ENFJ conversation is more about getting to a goal. The ENFP is more about understanding.
Very true, I think. I just ended it with the ENFJ dude I was dating (but we're going to be friends... I actually think that will be much better... less pressure, blah blah). And while he said he thought I was amazing and great and he could see us being great friends, he wanted to date someone who was a bit more mellow and "deeper." This took me aback. I realized that while I conversed on what seemed to be a superficial level (I just like to make people feel good and have the conversation take twists and turns and have silly banter), I realized he did not understand me at all. I am a VERY deep person... I have a well of emotions and feelings, but you have to know me well before I will let you into that part of me... I can actually get a little sad/depressing/bitter when serious... I just think it's an unexpected side. ANYWAY, ANYWAY... I think he thought I was a bit ditzy... very fun, but no substance. Which bothered the HECK out of me and I realized he just didn't GET me.
Also, with another ENFJ friend, she thinks she knows what I am thinking and she thinks she understands... and when we're getting along, she's pretty right. But if we're not in sync, she can be completely wrong and think she has me all summed up--but not at ALL. But of course, she thinks she is right because when has her ENFJ intuition led her wrong? And when I think about a lot of my ENFJ friends, I love them, but they do tend to feel that they are right all of the time. It's not just a "hey, I'm right" sort of thing, but it's a stating of their opinion as fact. And usually I accept it without even noticing. But of course, with MBTI, I have noticed it a lot more.
End of story: obviously there will be some areas of struggle (possibly, depends on the person), but I still think it's a good match. My closest friends are ENFJs and I love them to pieces!
