What instantly qualifies or disqualifies someone as a potential partner for you?

Personally, I quickly become very interested in someone who can be described as highly articulate. Their vocabulary, quick critical thinking, great understanding and reciprocation of humor, the way they deliberately yet subtly choose to word sentences to get specific points across and an ability to immediately come up with answers to complex questions…

I find conversations with people who possess these traits extremely satisfying, as they can go on for as long as you can imagine and give you both the freedom to go in depth about each other in ways that simply aren’t possible with other people.
