Do I Say That?

More laundry. I told Anna we needed to head downstairs and do some more laundry. She would prefer to stay in her room. That's not a choice, let's go girly. She expressed again the need to stay upstairs. I said, "Anna, that's enough, let's go." To which she replied, "Mama, I no think dat be a good idea. I no have enough money fo' dat." I wonder where she heard that phrase?
