[Charles sees a picture of himself playing with one of the white posts he frequently uses in his outdoor constructs]
Charles: What is that white thing?
Dad: Who is that in the picture?
Charles: Me.
Dad: And who was playing with the white thing?
Charles: Me.
Dad: And who knows what the white thing is?
Charles: I don’t know.
[Later we see an old picture of Charles sweeping the sidewalk with the big broom]
Dad: You’ve liked that broom for a long time, haven’t you?
Charles: [smiles] Yesssss.
