Baby (sitting on hallway floor, enthusiastically): "Waa, woo, gaarrgh!"
Mama (rushing out of the bedroom): "Qu'est-ce-qui se passe? Oh. It's an ant. That's an ant crawling on your leg. That's what they do. They're like crumbs but they move."
Baby: "Gaaah, gah gah!"
Mama: "Yes, now it's on your hand. Now it's on your arm... Let's go play with some blocks."
