lol, I did this with my ENTP friend. We hardly talk now but when we did, we'd talk for hours and hours and it was effortless. We had a few arguments (and they were pretty ugly :horor but most of the time we enjoy each other.I liked him much better when he balanced the Fe/Ne with Si, he was much more sane, but I think Ne was a real bonding point for us, and probably why we could have four hour conversations, excitedly feeding off each others ideas and comments, bantering back and forth, blah blah blah...sometimes to the point of talking over each other. It drove his mother c-r-a-z-y. I think it also started arguments between us sometimes though, that's the only bad thing.
It was more that he was so provocative. Even I had a moment where I wondered that. lolJTG1984 has a lot of Ne for an ISFJ which is why I think there were people who actually believed he was ENTP trolling as ISFJ, et al.
I think this is likely what happens but the two people can only appreciate it if they are open to being balanced.I think someone with a lot of Ne (Ne dom/aux, like NPs) are the people who have the easiest time bringing it out, just like SJs can bring out my Si, I swear. They're like bonding points. It's like being balanced by a person who understands a hidden part of you.
I don't know how I do it, anyway, I don't have a method. I'm just saying it does happen.
