My little Leo -- who will turn four next month -- went on a school field-trip to a farm the other day.
me: Did you see animals at the farm?
me: Did you see a doggy?
me: Did you see a kitty?
me: Okay, no kitty. What other animals did you see?
Leo: I saw a dinosaur.
me: Really? A dinosaur? Did you see chickens?
Leo: Yes. I saw chickens and a dinosaur.
