You've No Idea Who They Are
Okay, obviously you do. They're posted up seven stories tall on the building across from your office in their underwear. But hell no are you letting them know that. As far as you know, this chick Karlie is just an abnormally tall girl that's just as abnormally nice. And that guy sitting across from you just happens to have a jawline you could cut boxes open with. Totally normal.
If by some organic means you end up in a conversation, throw in a "Sorry - didn't catch your name!" to seal the deal, and schmooze your way into talking about anything other than what they do. As far as they know, you've never seen a movie, you don't like music, and pop culture completely escapes you.
