Don't know too many other INF's, except my mom (INFJ) So, with INFP I can really only speak about myself.
INFJ Likes:
-Easy to talk to. Likeable people.
-Funny
-Express their opinion without being rude or in-your-face about it.
-Patient and understanding.
Dislikes:
-Make me feel guilty. :/
-When I need to vent about a problem or frustration they always try to solve the problem instead of simply just listening or sympathizing.
INFP Likes:
-Ability to think outside the box.
-Childlike innocence.
-That we're the most romantic of all types.
INFP Dislikes:
-That we're the most romantic of all types. :/ (Can be problematic.)
-Socially awkward sometimes.
-Totally bipolar.
-Easily offended, take everything way too personally.
Like I said, I can only speak for myself...
