Fiction and non-fiction

I was standing by the church library while two wee girls were looking at the kids' books.

('Bible Fiction' means historical fiction and time-travel stories about Bible events.)

Child 1: In my school we can choose whether we want to read a fiction book or a non-fiction book.

Me: Which do you prefer?

Child 1: Fiction 

Child 2: Non-fiction, because it tells you about things that are real.

It made me think of that Neil Gaiman quote (where he was misquoting GK Chesterton):

Fairy tales are more than true – not because they tell us dragons exist, but because they tell us dragons can be beaten.

I did not confuse them by telling them this!
