From the article:<p>"Our body language is also different from mundanes.  We tend to not use eye contact nearly as often; when we do, it often signifies that it's the other person's turn to speak now.  This is opposite of everyone else.  In mundania, it's <i>breaking</i> eye contact that signals turn-taking, not <i>making</i> eye contact.  She demonstrated this on 
DDB; breaking eye contact and turning slightly away, and he felt insulted. On the other hand, his sudden staring at her eyes made her feel like a professor had just said "justify yourself NOW".  Mutual "rudeness"; mixed signals."<p>I find this to be really true.  Amazing I never noticed it before, but I often find eye contact dynamics to be a little bit awkward when talking to a non-geek, and I think this explains why.
