Introverted feelers dominants are very difficult to communicate with. In fact I believe they are notorious for being misunderstood, or never fully understood. They don't really understand anything outside of their ideas and have poor ability sharing their experiences. Let's speak about their language. Basically, everything they say is how they feel about something. So, basically, whatever comes out their mouths, you just have to mimic it till you feel they have strong emotions attached to that subject, and that is where you get them. They will never understand what you are saying based on what you are saying but will take the information and process it based on how they feel about the whole idea. My isfp sister, she is a religious one, Christian, that is her language. Every idea, even mbti, can be warped into Christianity and the Lord. My mother is infp, an is crazy, have had a few infp friends, they are all crazy, these ones are in their own worlds, the hippies and cat ladies that belive their ideas are the universal principles.
