Alright so. When I asked that I wanted to know if when you use Fi, you also try to understand everything that's inside you and everything the place and the people you are surrounded is affecting you. Not only what it is considered valued or worth-living for, but also their knowledge, their impact on others. What they are capable, what they are not. The social power and the management of the world. How they have come across with such points of view, the cultural, geographical and more reasons to get to know them, which will make you understand them more and judge them accordingly. But it seems that's more of your information gathering function, in this case Se.
NekoNinja, what you have answered had not so much to do, but maybe this good boy attitude helps you to understand people better, and maybe it is a behavior that is coherent with what you consider valuable. Am I right? RyRyMini, you mean that you can't talk about your values if asked? Like, you have them in your mind but the only way to see them clearly is acting accodingly to it when there's a situation that demands it?
In my case of Fe using, we want to know not only the person's values, but also their personality, the social and cultural background, their capacities. While we won't make a deep research in facebook and twitter to get to know this person (lol bad joke xD), we will try to grasp inmediately how this person thinks and why, in a very inmediate fashin, maybe that's Ni at work.
