So much hinges on their etype.
I don't know any infps, so...
(sx/so) enfp 1s blow me the hell out of the water, supernova style, especially wing 2s (more common than w9s?).
Able to match up with e3 enfps' rolling stoneness, stupid ideas with my stupid observations.
Not surprisingly, enfps aren't exempt from exhibiting an exaggerated set of personal ethics, artificial sensitivity like any other nf, but both they and infps have an especially tough time, particularly when e6, in identifying internal blind spots they denounce in others, avoiding Don Quixote shits around the bush.
e7 enfps often miss my unflagging optimism, quick to misinterpret dryness as pessimism, though it's all peaches before that point. I recommend spending time with them over me anyday. Know how to dress up in toucans, pleasant, good company, chug that wine baby. So long as you know how to consistently fake a smile, you're safe.
Generally easy, probably would go with either e3 or 7 (maybe 1) if all the doors were locked, though I feel something like a covert enfj with an oversized dustrag over my head, actively evaluating fuckall interacting or not, but usually interacting, directed, hardly ever not paying attention to everything else but whichever. Most people I know know know are intps; seems like there's a more productive dynamic happening there, with the enfp serving as a sort of sugarfree substitute for an esfp. Likewise, seems like there's more mutual intrigue, personally, with entps, though as an entourage of one, I'm not sorry for eating your uncle.
