I think people just like to hear something new, and often like to take things on board if they like it enough. Before I knew my brothers well enough, I would not share the same sense of values that I have today. They presented to me values like loyalty and pride, you have to fight for what you believe in, and take pride in yourself. I used to consider these qualities to be irrational or irrelevant. Sometimes people show qualities that I already have, but never realized how valuable they have always been. Just like that INFP suggested to Poki, you need to have a teacher or a guide to make the best of life. A student will excel with a lot more ease than someone who goes without. This is what we come to the forum to share, this is also what we are all doing now on this forum, giving perspectives and letting anyone make of it what they will. That's what conversation is, MBTI is a classification of flavour, just like saltiness and bitterness, sure it doesn't perfectly define the ultimately greyscale universe, but neither does saltiness and nobody has had any problems with that. It's been said before, people come in all sorts of flavours, just like cashews, onions and bananas. The only time when conversation sucks is when it's onesided, or there is nothing new to share. That's when you go and try a different flavour... which is not how marriage works lol, silly Christians.
