There's a family photograph somewhere of me sitting on the bottom step of the stairs, in my Woolies Ladybird dressing gown, drinking a mug of hot chocolate and peering at the murky picture.
I still remember my dad sitting next to me and telling me it was very important and that one day, I'd be glad I could say I saw it. He was right. It has allowed me to bore my kids senseless on more than one occasion.
