So two INTJs meet in bar, ok..., an art gallery. They are having a great conversation about the Jungian influence on the post impressionist (what ever that means). They discover that they're both INTJ and the sparks fly. Time flies, they're getting into it hot and heavy and suddenly they see that they are the only ones left in the gallery and it’s closing time. They turn and look at each other.
The first one says, "I know what you're thinking."
The second one says, "Yeah, I know what you're thinking too.”
The first one says, “Well then how about it?”
The second replies, “No. I need to think about it, first.”
The first nods, “Hmm, You’re right, I need to think about it too.”

Isn’t that hilarious?
I know. I just made it up. It needs work.
