The other day I over heard this conversation between Anneke and Lukas:
A: "Do you want to play house Lukas? I'll be the Mom and you can be the kid, but the Daddy's not here because he's dead."
L: "No! I want to be the Dad and you can be the kid and the Mommy's dead."
A: "That can't be Lukas because Daddy's are older so they die first."
Now that, folks, is what I call Toddlerlogical!
