I have a number of possible INFPs in my life - some I know well, and some are new friends.
Just for fun, what are some of the ways you form connections with other people? How do you like to form friendships? How do you communicate when forming new relationships with people? Do you keep things light and distant, or sharing deeply early on, playful banter, intensely personal topics, etc.
I can try to think of some more specific questions, but I like keeping things rather open, just so people are free to respond in whatever way is most relevant to them. Mostly I suppose just share with some of the processes you have experienced in forming friendships/relationships, things that have specifically turned you off, and how you might idealize the process.
