I've been friends with an ENFP for over ten years. We met while her husband was teaching at the Bible college where my husband attended/worked. It took me awhile to warm up to her, but apparently as soon as she met me, she knew she must have me as a friend.
We haven't gotten to hang out irl in years, but one of the things that was great when we did was that she is bigger than life. When we went places, it was like I magically turned invisible because she lit up the room. It was wonderful because it allowed me to be in the background and observe until I felt comfortable interacting. She thought I was being nice 'letting her shine' but I don't have to feel or try to be nice to do that. It's just my comfort zone.
I know I can be paranoid, but my ENFP friend's occasional paranoia seriously rivals and sometimes exceeds mine.
When you meet her, at first you think she's a brainless, bubbling butterfly, but then if you talk to her you realize she is brilliant. She is one of those people that have everything: looks, personality, brains. She would be stinking rich if she could focus or had better taste in men. She'll probably end up being rich eventually anyway. Rich or not, she's a generous person, with her affection, her energy, etc.
She and I share a lot of the same values and ways of thinking. She likes to talk and I like to listen. She tries to make herself listen to what's going on in my life, but it never really works. She gets bored and zones. But we can talk back and forth about abstract stuff pretty well. She likes the way I see through people and the weird way I sum things up. Talking to me helps her think clearly. She always has something interesting going on.
And I have to stop now or I'll be late for work.
