One fine afternoon I was walking along Fifth Avenue，____ I remembered that it was necessary to buy a pair of socks. Why I wish to buy only one pair is ____. I turned into the first sock shop that ____ my eye, and a boy clerk who could not have been more than seventeen years old ____. “What can I do for you, sir？”“I wish to buy a pair of socks.”His eyes glowed. There was a note of ____ in his voice.“Did you know that you had come into the finest place in the world to buy socks？” I had not been aware of that, as my entrance had been ____. “Come with me，” said the boy，excitedly. I followed him to the back part of the shop, and he began to haul down from the shelves box after box，____ their contents for my enjoyment.
“Hold on, young man, I am going to buy only one pair！”“I know that，” said he，“but I want you to see ___ beautiful these are. Aren't they wonderful？” ____ was on his face an expression of solemn and holy pleasure，____ he were revealing to me mysteries of his religion. I became far ____ interested in him than in the socks. I looked at him in amazement. “My friend，” said I, “if you can keep this up, if this is not ____ the enthusiasm that comes from novelty, from having a new job, if you can keep up this enthusiasm and excitement day after day, in ten years you will own every ____ in the United States.”
My amazement ____ his pride and joy in salesmanship will be easily understood by all who read this article. In many shops the ____ has to wait for someone to wait upon him. And when ____ some clerk does notice you, you are made to feel as if you were interrupting him. Whether he is ____ in deep thought in which he hates to be disturbed or he is chatting with a girl clerk, you feel like ____ for “being too rude”．
He displays no interest either in you or the goods he ____ to sell. Yet possibly that very clerk who is now so apathetic began his career with hope and ____. The daily grind was too much for him; the novelty wore off; his only pleasures were found outside of working hours. He became mechanical, he became incompetent, and then he saw younger clerks who had more zest in their work, promoted over him. He became sour. That was the last stage. His usefulness was over.
