I'm a social INFP which means I like meeting and talking to new people but I'm tired afterward unlike extroverts who gain energy from being around people. I talk with people easily not because I've suddenly become extroverted, but I've learned conversation skills, patterning, etc. They're just skills like bicycling or chess.
However, I do take on the behaviors of other types depending which Role I'm in. Everyone has a single Identity, but we have multiple Roles like father, son, sibling, employee, husband, writer, artist, etc.
As an employee, I exhibit INTJ behavior. When I'm by myself, I'm an INFP. When I'm with clients, I go into ENFP mode. I take on whichever behavior will make me most successful in that Role.
