My best friend is an INFJ. I honestly couldn't ask for a more loyal, trustworthy, and amazing friend, BUT sometimes it's difficult for me to understand her. I naturally feel the need to break the rules that need to be broken and have trouble taking things too seriously. I am hardly religious, if at all. She is very loyal to her parents, but some things that her parents make her do are ridiculous. She can't watch any PG-13 movies or YouTube videos that her mom hasn't pre-approved. She's super-religious, even though she doesn't try to change my views (which I really appreciate, since I've dealt with people who did). She also really underestimates herself. None of this has really affected our friendship until now. She spent the night the other night, and she acted so quiet, modest, and just plain good. I'm not saying it's a bad thing, it's just that I can't seem to ever get her to loosen up. I think a lot of it was the fact that she was out of her element. At my house, things really have no structure and we don't usually make much effort to be "polite". I really admire how true she is to her values and her loyalty to her family, but I just wish she would relax every once in awhile. Is this normal for INFJs?
