Flying monsters

Ella came out of bed to tell me she couldn't sleep because of the thunder. But it turned out it wasn't really the rumbling that kept her awake.

Ella - I'm scared the monsters are gonna come.
Me - If they come, I'll scare them away. But I don’t think they'll come.
Ella - The monsters live far away from our house, don't they.
Me - Yeah, I think they do.
Ella - They only live in Belgium. And that's really far away. And they don't let monsters on the plane, do they?
Me - No, they definitely wouldn't let monsters on a plane.
Ella - And not bad people either.
Me - No, they can't go on the plane.
Ella - But they let old people on the plane. Because they can't do nothing, can they?

I'm sure there is some logic in there somewhere.
