The Mayor

Me: Because I'm the mom and I can do whatever I want.

Donovan: No, you can't.... you can't... set things on fire!

Me: Sure, I can!

Donovan: Well, you can't... set the Mayor on fire!

Inventors

Jim: You are a great inventor! I love what you've done with these (Legos)

Donovan: Yeah, when I'm a grown-up all the other inventors are just going to stare at me with their mouths open like this (eyes wide, mouth open)!

Crying Eyes

Donovan: So, if you cry a lot your eyes turn red, right?

Me: Yep.

Donovan: So, what happens when red-eyed tree frogs cry? Their eyes must turn blue or something.
