They are on a roll my boys. Watching me attempting to squeeze through a tight spot between a car and a wall, they burst into hysterical giggles before shouting (yes, shouting - full volume, to make sure the whole street including the painter opposite and the Sainsbury's delivery man could clearly hear):
'You'll never fit through there Mummy! Your bottom's far too big.'
In the How to Make Your Mother Feel Good About Herself Stakes, they are firmly bringing up the rear (sorry, couldn't resist but I'm still feeling a bit delicate about the state and size of my backside so watch the puns... )
