Baxter: “When’s Amelia going to be three?”

Me: “Amelia’s already been 3; she’s 6 now and she’ll be 7 next.”

Baxter: “Are girls be three?”

Me: “Yes, girls and boys both turn three.”

Amelia: “Baxter, everyone in the whole world has been three. (pause) Well, unless they died when they were one or two.”
