A special technique, as used by Soccer Boy. A grumpy, sore-footed, tired Soccer Boy who had been dragged around the local shops for longer than five minutes.
I bumped into an old friend I hadn't seen for years in a crowded bookshop. We had a lovely chat while Soccer Boy grew increasingly twitchy by my side. I thought it was boredom, but, actually he was planning his revenge. He waited until my friend had left, and then asked loudly: 'Where did you meet her, mum? Was it while you were IN JAIL?'
We went home. Which was exactly what he wanted.
ps The Koala has never been, nor does she ever plan to be, in jail.
