I've known an INFP from age six up to now, but he's starting to get on my nerves. He takes everything extremely personally and seems to believe that life's all about him being against the world. He thinks that he's misunderstood, but doesn't do anything about it, instead he hides in his room and whines about being misunderstood.
These are some friends that were in my class for 10 years. Would probably not know them otherwise (we're SO different)
ESFP x3
ESTP
ENTJ (the only one I can stand atm)
ISTP
We're pretty close, since we saw each other almost every day for ten years, but nowadays I have difficulty standing them. They will only talk about the most shallow things, and I'd rather be at home doing something productive.
However, I got two new friends a while ago (about six months), and we get along great.
One of them is INFP, the other one is INFJ.
I actually like the INFJ more, we always have incredibly interesting discussions and seem to be able to talk forever.
The INFP is nice as well, but it's hard to discuss moral things with her, since everything I say that doesn't support her perspective is taken personally. I don't try to manipulate her into thinking like me, but it would be nice to be able to DISCUSS things calmly without her getting hurt and angry.
