Me: Tiago, It's time to sleep.
Tiago: I am sleeping!
Me: No, you're not. Your eyes are still open.
Tiago: I'm just pretending to be awake.

Tiago: Mom, Daddy's a genius!
Me: Really? Wow! How about me? Am I a genius too?
Tiago: Nope. You're a person.

Tiago: Mom, what are you doing? 
Me: Nothing.
Tiago: Oh. Let's play nothing together! 
Me: How do we play nothing?
Tiago: Like this.
