Glimpse inside Skipper's brain

Skipper is eating a sandwich, sitting alone at the dining room table with her hand-me-down Furby "sleeping" in a box beside her. I'm washing dishes in the kitchen, ten feet away.

Skipper: Mom, why did the Titanic sink?
Me: It hit an iceberg.
Skipper: But how did that make it sink?
Me: I don't know. It broke in half?
Skipper: But all six of its tanks filled with water. How did breaking in half make that happen?
Me: Sounds like you know more about it than I do.
Skipper: I keep checking a book about it out of the library but I always stop reading it because it makes my mouth hurt because I know what's going to happen.
Me: Oh.
