Are you guys closet goofballs? There's girl at work who I suspect might be an ISFJ. She seems really shy but we started joking with one another right off the bat and she has a rather off the wall sense of humor that makes me laugh. Someone once commented, "she's really quiet" then her close friend was like, "Are you kidding? She's the loudest person ever" (no it wasn't sarcasm.) What do you think?
