Voice from the child-seat.
I look in the mirror.
The FYO* is looking at his feet.
‘I’m wearing red socks.’ he says.
‘Are you? I didn’t notice. Are they warm?’
‘They make you have red toe-fluff.’
‘Really? Does it get between your toes and make them warm?’
‘No. It makes your toes easier to wiggle.’
(*now five, but still the FYO)
