I know I'm lagging behind the majority here, but I finally had my first direct encounter with a personal wearing Rayban spy glasses, behind the counter of an auto repair shop. It had a very weird effect on our interaction. I felt like I was performing- which, I possibly was. So I thought about dumb things like posture and making sure I summarized my questions and conclusions sufficiently. I think I subconsciously wanted it to be a smooth interaction, it case it was preserved for someone's posterity or edification. It all felt artificial like an unscripted comedy skit. If it did this to me, imagine how many people are feeling even a little bit that way, and eventually all of our social interactions could be very strange.
