So, the Uni I go to has a lot of INTJs... I'm quite fond of them.
They can be surprisingly sweet and adorable
(one of my INTJ friends recently asked me out, and things actually are going well
. And he's super endearing, considerate, and sweet. I'm actually very surprised at how sweet he is acting).
They are generally honest. Some of them have learned to be more tactful. Regardless, they will tell you there honest opinion of you. This is handy for someone as socially oblivious as I am. It allows me to relax and give my Fe a bit of a break, because they'll tell me if I did something dumb and inconsiderate.
The ones I know are incredibly loyal. They will move the world for their friends. They also expect a lot of loyalty from their friends. Once betrayed, they won't forgive. However, short of betrayal of trust, they'll tolerate a lot. I can be a complete idiot and they'll be okay with that (and usually laugh at me
).
I find them hilarious. ^_^ My INTJ friends and I are mutually entertained by each other, which works well.
