I'll give you an example. this one time, i had arranged with two friends of mine (lesbian couple) to go to a natural reservation outside of the city. we were taking their car, so i went to meet them at their house. when i arrived, my ENFJ friend was happy to see me, and arranging everything. but i sensed that she was being a bit bitchy to her INFP girlfriend. and when i was alone with the INFP friend, i realised that she wasn't happy. so the ENFJ friend had put on a show of happiness, when really things weren't alright. and i felt partially guilty, because i'd also replied in a happy tone, without knowing that the room wasn't full of happy feelings.
now, when someone is not happy or in pain, i feel their feeling. that's where my empathy comes from. so immediately i talked in private to my INFP friend: "hey, what's up, you're not ok?" - although, at the same time, i also felt like i shouldn't dig a lot, because it might be a private issue between the couple. but it pained me to see someone so sad and bottled up with emotions that were not being addressed at all.
so, already i didn't feel well. when we got to the car, my silent INFP friend finally talked. she said she was so very sorry for the situation (she trully was so embarrassed) but she couldn't pretend everything was alright, and she wasn't feeling in the right mood, and me and the ENFJ friend should go alone, without her, because she just ruins everything and she's worthless blah blah. i said right away: "sure, but we don't need to go at all, don't worry, it's not your fault, if we're not all in the mood, there's no point in going, we can do it another time ". this is my way of solving things.
i was surprised by the reaction of my ENFJ friend, totally different. she said to her girlfriend: "oh shut up, get in the car and let's drive. it seems like i'm the only adult here, the only one who takes care of things". so both me and the INFP got in the car, and i felt like a girl who'd just received a command by a parental figure. i also felt awful for my INFP friend, and i tried the whole trip to acknowledge her feelings (by supporting her when she was talking, etc).
but when we arrived to the destination, my INFP friend was happy. she was in the nature and she was happy. and i was surprised again, because i saw how one way of solving issues that is so different to mine, can also work out. but, at the same time, it really got me this Fe way of solving issues, that is about ignoring the feelings that are not useful to you, and i wondered if my friend was ok or just hiding her feelings, still.
