Much like this story, Salvatore uses his imagination, back-ground knowledge, and infinite wisdom to understand and manipulate the world around him.
While he was helping me cook dinner the other night, I told him that he was my favorite son.
He got extremely quiet.
Then he asked me, "What about Valentina? She's not your favorite son?"
(Ahhhh...this is where I am so blessed to have one of each.)
I answered, "She is not my son, she is my daughter. Because she is a girl. You are my only son." He started shaking his head and then his finger (he gets that one from me) and replies, "No, no, no, no. Valentina is not your daughter. She is MY daughter. And she's my wife. You have daddy as your wife and she is mine, got it?"
I think I got it.
