Nellie Oleson : I wonder why Laura Ingalls doesn't come in the store anymore?
Willie Oleson : Because she's too poor to buy anything - that's why!
Nellie Oleson : So's her father. Mother says he can't even afford to pay what he owes in the store. He just spends all day cleaning up after horses.
Laura : My pa works hard.
Nellie Oleson : So does a mule.
