In terms of sensitivity, as far as I've observed, is that ENFP's really don't get into the tiny details of things. Everything is much more in general and put into a larger perspective. The INFP goes deeper into a thought or comment. After a conversation, I'll reflect back on it, too many times (I hate that), and I'll chop up each little sentence and sometimes be able to ascribe 3 meanings to it, and I'll decide how I feel about it, and even when I don't value someone's thoughts, I can still find away to be ticked off about it. Then, I'll get stuck on that one little sentence and have trouble letting go of the implied slight. That's not to say that I always do it, but I have and that's not an ENFP thing. That Ne being your first function makes a big difference as far as not dissecting sentences.
It is strange about ENFP's that they can be outwardly focused and inwardly at the same time. From what I observed, the ENFP was putting all her thoughts and problems out there as in "everyone look at it," and we do, and tell her what we think about it, but she rejects input, or it seems that way. She'd have all these problems that never get solved because she had an idea about how she wanted things to be, and insisted that they were that way (no matter what anyone told her), and therefore, our input was not applicable/invalid because it doesn't fit her vision. So, she would only approach problems in a way that fit her vision of them, which was a fairy tale.
I accept input and have to come to terms with it. It can be overwhelming if there's too much of it. And I always have so much doubt as to whether my truth is correct and I constantly adjust my worldview to match what's coming in. That's part of why I can be so quiet. I don't want to be stuck in my thoughts, thinking about one stupid sentence, when I'm trying to accomplish stuff.
I hope none of that was insulting. I don't know what it feels like to be inside the ENFP mind, just what I observed.
