I like having a ten-year-old in the house, because in the space of ten minutes the conversation can move from this:

‘Mum, I was just wondering, when you’re doing a story, do you like to use mostly declarative or imperative sentences?’

to this:

‘Mum, have I got a chip on my nose?’

‘No.’

‘Cool. That means I got it in my mouth. Can you do that? Throw a chip up in the air and get it in your mouth first time?’
