Caspian Quote of the Day

This one happened over dinner tonight. Caspian was drawing, and Susan was telling me about her day:
Susan: "I got stuff to make a girl dolly for Caspian to go with his boy dolly."

Josh: "I thought his dolly was a girl?"

Susan: "Nope, he's just been saying 'she' a lot. Hey, Caspian, I'm going to make dolly an extra part to make sure you know he's a boy. Do you know what part?"

Caspian (without skipping a beat): "A chromasome."
