small talk

Adina recently had an entry in her livejournal about small talk. This reminded me of my ride back from Great America with Simon yesterday. As we drove along in the car, having spent all day together, he says, "See the signs on the side of the road? They're green. In Europe, they're blue." I have no idea if he was planning to expound on this topic. But he didn't. And I had no reply. I turned up the radio instead.
