" I nodded my head at him and gave a small wave of acknowledgment, the gesture communicating, Oh there you are, good. I started walking over. His head turtled in a fraction and his body tensed in the internationally approved reaction to being spotted on surveillance. It’s hard to describe, but it looks a little like what a gowned patient does when the doctor picks up a long instrument and advises this might be a little uncomfortable. He looked around, then back to me, doing a decent imitation of someone wondering, Huh? Was that me you were waving to? Do we know each other? "
