Em: Mummy! Come and wipe me!
Me: ok, coming.
Em: no, wait, don't come yet.
Quiet for a few minutes.
Me: are you ok? What are you doing?
Em: I'm ok. I'm just waiting in case the toilet flies me away somewhere.
Me: you're what?
Em: I wished the the toilet might fly me away somewhere!
Me: you'd better hope it doesn't; that might get a bit messy!
