I used to think I was an introvert, but I think I'm actually an extrovert. I love short, spontaneous, happy interactions - like in line at the coffee shop or with a waiter or waitress. But "socializing", no. Not interested. It's SOOOOO slow and so petty and SOOOO illogical. And people are often just faking it and I don't understand why they do it. What's the point?
BUT
I love working with people who love their work so much that they forget about all of the social acrobatics. I don't want to be "friends", I just enjoy working with them, very much. No talk about personal matters, no talk about other people's personal matters (gossip), no covert intentions or manipulation, no fear of embarrassment - just happy people or, more accurately said, people who are in "happy mode" - doing what they love doing. But THEN they want to "get coffee" or otherwise "hang out". Socially. No. That's when I make my excuses and leave.
