When my twins were about 3 or 4 we stayed at their cousins for a week. One afternoon we went out for a drive and as we passed a pub a little voice at the back of the car said "What's that pub called, Dad?".

"That's 'The Sun'," I replied.

"But what's it called at night, then?"

(and a long time ago my sister (8 at the time) asked "If you have a heart attack, does that mean you're dead for the rest of your life?")
