A conversation...

This is what my sister and I heard from the back seat on Saturday:

F (d's cousin, almost 2): "you sleep?"
D: "Dere doggie over dere."
F: "you sleeping?"
D: "Dere doggie over dere."
F: "you sleeping?"
D: "Dere doggie over dere."
F: "you sleeping?"
D: "Dere doggie over dere."
F: "you sleeping?"
D: "Dere doggie over dere."

This continued for about 5 minutes without any changes. They were both very earnest in trying to communicate. Very strange.
