Fe vs. Fi quadras and people: Fe is jokey, playful, non-serious, clubbish. They can take the serious and turn it frivolous. For a Fi person this is disconcerting because they're inclined to take everything as meaning something even when joking around. "I didn't mean anything by it" is more likely to be said by Fe quadra folks than Fi, and "Oh, I thought you meant" is more likely to be said by Fi quadra folks than Fe. My powers of communication I'm afraid = fail right now.
Basically if you can be in a relationship with an ISTp and not get bewildered that they never seem to change emotion, you might be ENFp. If you can be in a relationship with an ISFp and not get bewildered by their shifting emotions and vagueness, you might be ENTp. But only might (: Obviously both can be quite happy with their semi-duals as well and adjust and learn to understand each other, though I think an ENFp-ISFp matchup would work better than ENTp-ISTp in the long-term.
