TEXT B Feld, the shoemaker, was annoyed that his helper, Sobel, was so insensitive to his reverie that he wouldn’t for a minute cease his fanatic pounding at the other bench. He gave him a look, but Sobel’s bald head was bent over the last as he worked, and he didn’t notice. The shoemaker shrugged and continued to peer through the partly frosted window at the near-sighted haze of falling February snow. Neither the shifting white blur outside, nor the sudden deep remembrance of the snowy Polish village where he had wasted his youth could turn his thoughts from Max, the college boy (a constant visitor in the mind since early that morning when Fold saw him trudging through the snowdrifts on his way to school), whom he so much respected because of the sacrifices he had made throughout the years—in winter or direst heat—to further his education. An old wish returned to haunt the shoemaker: that he had had a son instead of a daughter, but this blew away in the snow for Fold, if anything, was a practical man. Yet he could not help but contrast the diligence of the boy, who was a peddler’s son, with Miriam’s unconcern for an education. True, she was always with a book in her hand, yet when the opportunity arose for a college education, she had said no, she would rather find a job. He had begged her to go, pointing out how many fathers could not afford to send their children to college, but she said she wanted to be independent. As for education, what was it, she asked, but books, which Sobel, who diligently read the classics, would as usual advise her on. Her answer greatly grieved her father.A figure emerged from the snow, and the door opened. At the counter the man withdrew from a wet paper bag a pair of battered shoes for repair. Who he was the shoemaker for a moment had no idea, then his heart trembled as he realized, before he had thoroughly discerned the face, that Max himself was standing there, embarrassedly explaining what he wanted done to his old shoes. Though Fold listened eagerly, he couldn’t hear a word, for the opportunity that had burst upon him was deafening.He couldn’t exactly recall when the thought had occurred to him, because it was clear he had more than once considered suggesting to the boy that he go out with Miriam. But he had not dared speak, for if Max said no, how would he face him again Or suppose Miriam, who harped so often on independence, blew up in anger and shouted at him for his meddling Still, the chance was too good to let by: all it meant was an introduction. They might long ago have become friends had they happened to meet somewhere, therefore was it not his duty—an obligation—to bring them together, nothing more, a harmless connivance to replace an accidental encounter in the subway, let’s say, or a mutual friend’s introduction in the street Just let him once see and talk to her, and he would for sure be interested. As for Miriam, what possible harm for a working girl in an office, who met only loudmouthed salesmen and illiterate shipping clerks, to make the acquaintance of a fine scholarly boy Maybe he would awaken in her a desire to go to college; if not—the shoemaker’s mind at last came to grips with the truth—let her marry an educated man and live a better life.
