It seems like NTs aren't that interested in quirks. They are more interested in finding common ground and socializing in a give and take, friendly way. If they start talking about how they differ from the norm, it may mean someone might take issue with it. Someone might exclaim, "YOU DO WHAT!?!", and then make a wise crack and giggle nervously, but, when said quirky person isn't around, someone says, "She seems kind of crazy. Did you hear what she said she does?".
One time, I took some clothes of mine that were wet, because they just came out of the washer, and put them on clothes hangers and, then, looped the hangers over branches belonging to a backyard tree. It was a great way to dry the clothes without a clothesline, but the next door neighbor could see them from her backyard and thought I was insane. She couldn't figure out why on earth I would turn my tree into a clothes closet. She had no idea the clothes were wet.
But, that's just an NTism and it's why they don't like to think outside the box and don't like to discuss their "quirks". Since they are so busy calling other people "weird", they don't want to give other NTs an excuse to call them that. They are very aware of what makes other NTs tick and they don't want what they do to others who are "quirky" to happen to them. They don't want other NTs to call them "crazy" and "weird".
