As we pull into the driveway of Hayden's school, one of the other mothers (who without fail looks like she's walked from the pages of a fashion magazine at 7am every morning) walks down the lane to her car.
Hayden: Joshua's mummy is beautiful!
Inside Lucy: strange pang of jealousy
Lucy: Yes, she is. Do you think your mummy is beautiful? (I bait him, smiling back at him hopefully.)
Hayden looks at me pensively for a moment, truly considering my question.
