Final answer:
Mama's joy at receiving a $10,000 check quickly turns to worry due to the potential problems and responsibilities associated with such a significant sum of money.
Step-by-step explanation:
When Mama learns that the postman brings a check for $10,000, her initial reaction is one of overjoy. This feeling is natural because the sum represents a significant windfall that could have a substantial impact on her family's life. However, her emotions quickly shift to worry. This worry likely stems from the knowledge that such a large sum of money can bring about significant changes, and not all of them are positive. With more money, comes greater responsibility, potential conflicts over how it should be spent, and the fear that their lives may change in unpredictable ways.
The check for $10,000 is a life-changing amount of money, especially for a family that may not be accustomed to having such financial resources. Mama's conflicting feelings underscore the complexity of sudden wealth and the recognition that money can solve certain problems while potentially creating new ones.
