" Perhaps we were looking strained in our manner, because I noticed we had attracted the attention of a little man who sat on a sofa not far off. I tried to outstare him and that was easy. He had a long moustache and fawn-like eyes and he looked hurriedly away: his elbow caught his glass of beer and spun it on to the floor, so that he was overcome with confusion. I was sorry then because it occurred to me that he might have recognized me from my photographs: he might even be one of my few readers. He had a small boy sitting with him, and what a cruel thing it is to humiliate a father in the presence of his son. The boy blushed scarlet when the waiter hurried forward, and his father began to apologize with unnecessary vehemence. "
