It was quite late at night. I was reading a newspaper in my room when I heard someone knocking at the door. I opened it and saw a young man with glasses standing there. Of course, I didn’t know him. He said that he was a friend of my sister’s and wanted to have a talk with her. I wanted to know if my sister had such a friend，but I had to let him in.
As he talked, I found that he knew nothing about my sister. Then I came to know that his words were not true. Suddenly my sister came back and the young man was so surprised that he didn’t know what to do for a moment. I caught the man by the arm at once while my sister was calling the police.
