Nearly two decades has passed, I still remember my favourite professor, James Sehwartz. Whenever he smiles, it’s as if you’d just been told the funniest joke on earth. Almost all his students are his friends, and almost all his students know his life story. When James was a teenager, his father 36 him to a fur factory where he worked . This was during the Great Depression. The 37 was to get James a job. James entered the factory, and immediately felt as if the 38 had closed in around him. The room was dark and hot, the windows covered with dust, and the 39 were packed tightly together, running like trains. The fur hairs were flying, 40 a thickened air, and the workers, 41 the pieces of fur together, were bent over their needles 42 the boss marched up and down the rows, searching for them to go faster .James could hardly 43 . He stood next to his father, frozen with fear, hoping the boss wouldn’t 44 at him, too.

He made a 49 that he kept to the end of his life: he would never do any work that brought 50 to someone else, and he would never allow himself to 51 money off the seat of others. “What will you do?” his mother, Eva, would ask him. “I don’t know,” he 52 say. He ruled out law, because he didn’t like 53 , and he ruled out medicine, because he couldn’t take the 54 of blood. “What will you do?” 55 , my best professor I ever had became—he thought it was the job not to hurt anybody.
