このお話はまとめるとどういう話なのでしょうか？

Mama's Bank Account (1) I am Katrin. When I was a child, all my family lived in a small house in San Francisco. My family members were Mama, Papa, my elder brother Nels, my younger sisters Christine and Dagmar, and I. We were immigrants from Norway. I remember that every Saturday night Papa brought home a little envelope with his pay in it. Mama would sit down by the kitchen table with a serious look. She was counting it out. There would be several piles of coins on the table. "These are the rent," Mama would say, and set aside a big pile of coins. "For the grocer." She set aside another pile of coins. "For Katrin's shoes," and Mama counted out the coins. "I'll need a notebook this week." Nels said, and Mama put aside a ten-cent coin. At last, Papa would ask, "Is that all?" Mama would nod and say, "That's good. We don't have to go to the bank to withdraw money."
