"Good girl"

Thomas' laughs are infectious. He laughs at really silly things, not all of them appropriate, but today he laughed at something I said. Greta did something that I responded to with "good girl". He laughed like it was the most hysterical thing he had ever heard. Of course, I then had to continue saying "good girl" over and over again to his continued laughs. Poor Greta. I think it probably confused her a bit.
