I've run into this before. It's so often the case that I end forum topics because of it. I don't care about what the mbti says, Js and especially EXXJ's are the most judgmental of all the types. I really hate when I'm hanging out and I want to express my thoughts and I realize before I open my mouth that they're critical. I hate that that's my knee-jerk reaction. I don't like the idea of constraining the way that others are. I just like the idea of guiding people towards activities and ways of thinking that would be beneficial to them (in my mind at least.)
But yeah, me and my ENFP friend were talking about headphones and I had just gotten over the ear ones. I had been using the stock buds that came with my mp3 player but the SQ sucks. My Fe was torn between wearing the over the ear ones in public or staying with the buds cuz I think that people with fullsized headphones in public are kinda douchebaggy. I told my friend this and he got offended and as we continued to talk he got more defensive about other stuff we moved onto.
Point is, that's why I hate being spontaneous. Fe spontaneously judges those around me.
P.S. you spelled "definitely" wrong! What a dumbdumb head!

*shut up Fe* Sorry about that!
