1. What is a "spare room"? (no idea why they asked this, we have had a spare room for several years and referred to it as such).
2. What is the "rush hour"?
3. If you have three thousand pounds, are you rich?
4. Why do exams make you do the answers in a few hours? Why can't you have all day?
And the funniest one, rather loudly in church on Easter Sunday (yes I know, a rare circumstance in this family):
"Is the (communion) wine good?"
*Usually, either at bedtime (delaying tactics) or when I'm trying to board a train or park the car.
