Reading Passage:

I looked on anxiously at the clock: he was late, it was midnight and I was worried to death. What could I do? If I rang the police and then just he turned up on the doorstep I'd feel such a fool. I knew I had to pull myself together, so I put the kettle on and made myself a cup of strong black coffee to calm my nerves. Suddenly the door bell rang and somehow I knew that something dreadful had happened. I opened the door, "Mr. Smith? I'm Constable Jones. I'm afraid there has been an accident -- " I cannot remember anything about the next few hours; it was just like a nightmare. I just could not believe that it was happening to me. Everybody was very kind, of course: they did what they could do to help and everyone said that time was a great healer. My neighbours were marvelous -- they could not do enough for me. But Rover, run over by a bus! Tears kept on rolling. No other dog would ever be the same.
