You're not a cat, Daddy

P and Christian go for a walk in the evening, to give me some peace from the chatter-box.

They come across a cat.

P: "Meow, meow, meow.. meow" (at the cat).

C (matter-of-factly): "You are not a cat, daddy."

P (bemused and surprised): "Oh? Then what am I?"

C: "You are a Daddy!"
