| Every Saturday night Mama would sit down by the table and count out the money Papa had brought home. Mama would carefully divide big groups for the housing, and food, and one or two coins for Nels or 1 -Katrin to buy notebooks. With 2 interest we would watch the money becoming less and less. At last Papa would ask, "Is all?" When Mama nodded, we could relax a little. For Mama would look up and smile, "Is good," she'd say, "we do not have to go to the Bank.” It was a wonderful thing, that bank account (银行账户) of Mama's. We were all so proud of it.It gave us such a warm, 3 feeling. When finishing school Nels wanted to go on to high. "It will cost a little money," Nels said to Mama. We gathered around the table watching a box in front of Mama. This was the "Little Bank" -used for unexpected situations. Nels had it all written out. So much for what he would need. Mama looked at the 4 for a long time. Then she counted the money in the Little Bank. There wasn't enough. "We do not," she said to us gently, "want to have to go to the Bank." We all 5 our heads. "I'll work in Dillon's shop after school," Nels 6 . Mama smiled at him. Papa said, "Is not enough.”Then he took his pipe out of his mouth."I give up smoking," he said. Mama 7 the table and touched Papa's hand, but she didn't say anything. "I will mind the Elvington children every Friday night," I said. "Is good," Mama said. We all felt very good. We had passed another milestone（绊脚石 ) 8 having to go downtown and draw money out of the bank. So many things,I remember, came out of the Little Bank during the past 20 years. Even during the Strike（罢工）,Mama wouldn't let us worry too much. We all worked together 9 the important trip downtown could be put off. The day the Strike was over and Papa 10 to work, I saw Mama stand a little straighter. Last year I sold my first story. I hurried to Mama's and showed her the check. " For you," I said, "to put in your Bank Account. " "Is no 11 ," Mama said. "In all my life, I've never been inside a Bank. " And when I didn't-couldn't-answer, Mama said 12 ,"Is not good for little ones to be afraid-to not feel safe. " | ||||
