阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
One day, my brother and I were alone in our apartment. The reason was that my parents had both gone for a ball party and had left me in charge of everything. I was doing my homework while my younger brother was watching TV. All of a sudden, the doorbell rang. Ding-Dong! Ding-Dong! My younger brother had rushed to the door before I decided to answer the door. We both thought that our parents had come home. As a result, he unlocked the door and opened it.
Outside of the house stood a man who wore a black raincoat and black rubber boots. He looked no different from other people and he said that he was a salesman and asked politely if our mother or father was at home so he could talk with them.
Without any thinking, my brother said, “No.” He asked if we would like to buy some comic books, which he was selling. I quickly explained to him that we were not supposed to buy anything without our parents' permission. However, it seemed that he was not willing to follow my advice and he had an intention to enter our house.
Then, I realized something terrible would happen. As I was about to close the door, he forced his way into our house. He took out a knife and forced me to tie up my brother's hands with some rope which he took out from his pocket. I tied up his hands but I tied it in a special way so my brother could untie himself as we often did. The man then tied my hands up and locked both of us in thekitchen.
Soon, he went upstairs to search the bedroom for something valuable. I managed to teach my brother to untie the roop on his hands. He then untied me. I rushed to the telephone to call the police, but line was dead.
