Out of the mouths of babes

When my granddaughter emma was small, her parents took her on a tour of the mines in Cornwall — not much fun for a four-year-old.

When they finally got to the end of the tour, the guide asked: ‘Any questions?’ emma put up her hand as high as it would go to ask: ‘how do we get out of here?’ Doreen Bishton, Prescot, Merseyside.
