Dear Diana,

Thank you for the lovely day we have with you. It was so kind tor you to let us bring Anne's friend. Gina. Unfortunate, the only problem was the journey home. There had been a terrible accident on the highway and, for a result, there was a long line of traffic for at least six mile. In the end, we drove to a service station and waited there unless the road was clear. In the car park Gina nearly got knocked over as a car drove out far too quickly from behind a lorry. They finally dropped Gina off at her parents' and made our own way to home.
