I tend to gravitate towards NTs and INFs for friends. I have almost no S friends.
My Mom has tested ISTJ, my dad I'm guessing is an ISFJ, definitely ISxJ. I respect them both immensely.
My Mom is actually the one who got me into MBTI. She gave me the test when I was too young to read all of the words myself, and then i asked for another copy this year during break. I thought that I'd have changed a lot since I was that young, but my results were almost the same, except a lot more E.
