As George and I sat at the sidewalk table to play chess in the evening chill a pudgy, middle-aged Asian man stopped to leer at us. He rocked back and forth on his heels, giggling, brandishing a cigarette. I thought maybe he just wanted a light but it was lit and shedding ash. We didn't address him and George did a particularly good job of continuing our conversation unperturbed. The man rocked and giggled for a few more seconds and walked away.
