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.
