I enjoy this aspect of my duals, their humor is highly entertaining, even though I can see how it has many ethical slips in it (blunt, offensive, etc), but I can recognize when certain things have gone too far. Fi is able to recognize those lines between good/bad in a evolving/subjective and adaptive way. Once I know that you're a good person and what you say is not meant to hurt or harm any one I adapt to your ways and let you be who you are and promote social bonds. For instance, I'm able to ease the tensions of others who get offended by ESTj's bluntness/gruffness by communicating to them that that's just your type of humor, keeping your friends close by you (making sure they don't get offended and cut relations with you); helping you promote good social bonds.
In duality, you're supposed to be you and your dual accepts you as you are, but is able to take full benefit from those special abilities that you have...Te for me, Fi for you.
I'm very happy and content to be duals with such wonderful, sensitive, smart, organized, logical duals; You
