By contrast, an INFP rejection is more like the disagreement Heart and I are having about taking a principled stand. We're maneuvering a bit and testing. If we decide we want to go at it, we'll remain congenial for a while but then we'll finally break out the long knives and really start carving each other up.
But FWIW, INFPs at INFP-GC complained about my communication style as well. I'm a bit more "in your face" than most INFPs, I believe.
Finally I can't take it any more and I sit down and write it. But by then it's fully formed in my mind and I can just vomit it out on the page.
