Social Experiment

Earlier this year I made an interesting discovery: You're walking down an empty street, and since it's Dawson, you walk in the street. That's irrelevant, but its the setting. Anyway, the idea is that if someone, or in my case, a couple, walk along the street in the opposite direction, you might be tempted to look away as they pass by. As I told myself this, we walked closer and I promised myself that I would not look away. But for some reason, our brains do not allow us to look straight ahead unless we are purposefully ignoring the others around me.
Back to the social experiment. I'm walking down the street, promising myself that I won't pretend to occupy myself with some uninteresting object as I pass the unknown couple. Just before we pass each other, both the man and the woman look to my left, pretending to have noticed something interesting on the far side of the road. Despite myself, I glance to the right.

I leave it up to you to assess the significance of this behavior.
