Me (from the back seat): Oh my god! We just passed an elephant in a truck! There was an elephant in that truck!
My mum: Really? In a truck?
Dad (points to another truck with an elephant painted on): Did it look like that?
Me: No, it was a real elephant!
Dad: Was it big?
Me: It was an elephant!
Mum: How could it get up there?
We lapse into companionable road trip silence.
Mum turns to dad (conversationally): Did you put the bag of rum in the boot or is it in the back seat?
