That's interesting. No one ever thinks I'm very friendly at first because I never really engage with them unless I find them intriguing for some reason. If they approach me I will most likely be very friendly, but I'm fairly reserved amongst people I don't know.Furthermore, and in line with substitute's anecdote, the differences between me and my INFJ friend show in how we express our feelings to others. On the surface, she is much more friendly and willing to reach out to others and connect (even at her own expense sometimes).
An INFJ not following up on promises? Blasphemy!This leads people to think that she's the nicer, more pleasant one. Then they react badly when she's not in the mood and won't go through on things that she promised she'd do earlier when she was in a good mood.
