I had managed to sell all my papers and was coming home in the snow. In downtownNew York, workers were pouring homeward in the twilight. I marched among thousands oftired men and women whom the factory whistles had unyoked.        I met my father near Cooper Union. I saw him, a hunched, frozen figure in an oldovercoat standing by a banana cart. He looked so lonely. The tears came to my eyes. Then hesaw me, and his face lit with his sad, beautiful smile.       “Ah, it’s Mikey,” he said. “So you have sold your papers! Come and eat a banana.”I refused it. I felt it crucial that my father sell his bananas, not give them away. Hethought I was shy, and coaxed and joked with me, and made me eat the banana. It smelled ofwet straw and snow.       “You haven’t sold many bananas today, Pa,” I said anxiously.        He shrugged his shoulders. “What can I do?” No one seems to want them.       It was true. The rusty sky darkened over New York buildings； the tall street lamps werelit； innumerable trucks, streetcars and elevated trains clattered by. Nobody and nothing in thegreat city stopped for my father’s bananas.        “I ought to yell,” said my father dolefully. “I ought to make a big noise like otherpeddlers, but it makes my throat sore. Anyway, I am ashamed of yelling. It makes me feellike a fool.”“I’ll yell for you, Pa,” I volunteered.         “No,” he said, “go home； you have worked enough today. Just tell Ma I’ll be late.”         But I yelled and yelled. My father, standing by, spoke occasional words of praise, andsaid I was a wonderful yeller. Nobody else paid attention. Thousands of strange, silentfigures poured over the sidewalks in snow. None of them stopped to buy bananas. I yelledand yelled, but nobody listened.         My father tried to stop me at last. He consoled me with a big smile, “That waswonderful yelling, Mikey. But it’s plain we are unlucky today! Let’s go home.”        I was frantic, and almost in tears. I insisted on keeping up my desperate yells. But at lastmy father took me firmly by the hand and led me home.
