^ To add a bit more....Fi-ers may not instinctively pick up on the sort of universal appropriateness Fe picks up on, but we do pick up on individual standards. So if you set the tone, then we may know how to proceed. If you call a lot or at certain times of day, I think Ne sees patterns & Fi devises a general concept of how to deal with you. Like skylights, I'm sort of petrified of annoying people & for every reason to call I may think of 5 not to; and it's probably bad past experiences blown seriously out of proportion in my mind due to hypersensitivity. I have some social anxiety though, but it seems like for even non shy NFPs there's some over-thinking involved in relationships, and it helps when the other person is direct about what they'd like/need. I find myself a lot more flexible than others, so if they call me, then I am usually cool with it, but I find other people have all these weird rules, and I'd rather to wait & see what they are before inadvertently crossing one.
