Joey: "I have a lot of friends."
Me: "Yes you do. You're a friendly guy."
Joey: "And my brothers are my friends too. And my baby sister is my friend too."
Me: "Your baby sister?"
Joey: "Yep. My baby sister is my friend too."
Me: "Honey, you don't have a baby sister."
Joey: "Uh-huh! I asked God for a baby sister, and He said 'Yes'!"
Me: "Oh. Ohhh-kay."
