Conversation with my 4 years old niece
Me: What are you cooking?
Niece: I'm a princess.
Me: Oh I see.
Niece: I'm a princess so I don't cook. (in a very firm tone)
Niece points to a slightly older boy who was playing with her.
Niece: He's a King.
Niece: He's a King so he cooks for the princess.
hehehehehe! Now who says children aren't smart.
