"Mom, what do kangaroos do when they get scared?" asks Jessa. "I don't know," is my reply. "Do kangaroos bite," she asks. "I don't know" is once again my reply. "But what do they really do if they are scared?" she asks, annoyed that I don't know the answers. "I really don't know Jessa," I say. "You aren't a kangaroo are you mom," Jessa concludes and lets the subject rest.
