Evan: What is he holding?
Me: He’s holding a brain.
Evan: It looks like a mouth!
Me: Yes, it does look funny. But it’s a brain.
Evan: What’s that?
Me: It’s in your head. I have one in my head. Everyone has one in their heads. They help you think and do things.
Evan: It’s not in my head! There’s nothing in my head!
Me: (giggling) You have one, I promise you.
Evan: Wait! Master Mantis is in my head!
Evan: He’s giving me candy!
Then Evan stared at me, wondering why I was laughing so hard.
