Ben and his wife Susan were on their way to have dinner with their friends. It was a dark,windy night, and they did not know the way very well. They drove through a town until they found what they thought was the road to Dorling,where their friends lived. But it soon became clear that they were not on the road to Dorling at all. The road that they were on was getting narrower,and there were no other cars on it. The wind was blowing harder with every minute that passed.

They came to a small village .They drove past a church and then two houses without lights on. There was nobody about to tell them where they were,or where the road went. Just then,Ben saw a telephone box,twenty meters or so further on. While he walked back along the road to see if there was a name outside the church,Susan telephoned their friends and told them that they were still on their way.

Their friends were just saying that the dinner was already getting rather cold,when Ben came back to the telephone box,his head down against the wind. He said that there was a tree lying across the road,and that the telephone lines were down. Susan heard nothing more from their friends about the dinner.
