Zoe: Once upon a time there was a mouse who got stuck in the mud. Another mouse came along and helped him out. But there was a dangerous moose watching them and when they got out of the mud he chased them and caught them and ate them up. The end.
Mommy: Wow! So what’s the moral of the story? Don’t get stuck in the mud?
Zoe: No, it’s be fast. Because the mice were really slow.
