Wil: Yeah, the monsters live on moon up in sky. So you're gonna need get the telescope so I can look at the moon very far away in the sky.
Me: How did the monsters get on the moon?
Wil: They found spaceships then flew up to the moon.
Me: What do they do up there?
Wil: They were trying find food.
Me: They were trying to find food? What kind of food?
Wil: They were trying find.... berries!
Me: Berries on the moon, wow. Are there lots of berries on the moon?
Wil: Yeah, but (can't understand what he said) on the moon. But you're gonna need get telescope for me and look at the moon.
Me: We'll have to have Daddy make the telescope work and then we can look at the moon. Do you like looking at the moon?
Me: Tell me more about the monsters on the moon.
Wil: Well, they were trying to find a roof, but there wasn't a roof. They need go inside the moon and see if there was a roof. But we just have roof, but not the moon. (Sam made noise... ) scary.
Me: It's scary? It's scary on the moon?
Wil: Yeah, because we might see monsters. (I think that's what he said. Sam was making a lot of noise.)
Me: Is anyone else up on the moon?
Wil: No, just the monsters.
Me: Just the monsters? Do the monsters ever leave the moon or do they just like to live there?
Wil: They like to live there.
Me: So if you see a monster do you tell them they need to go home to the moon?
Wil: Yeah... But he won't because he might get me and take me away and fly up to the moon.
Me: I don't think they're going to take you up to the moon.
Wil: But they might see me and take me up to the moon.
Then he got distracted, although he remembered to ask about the telescope again. I might just have to try my hand at a children's story. And I would love ideas for assuaging his worry about monsters taking him to the moon.
