It was Sunday afternoon. My brother and I were alone at home. Suddenly the doorbell rang. My brother thought that it was our parents, so he opened the1quickly.
A tall man wearing a black raincoat stood outside. He said that he came to sell books and asked politely, 2 our parents were at home.
Without thinking, my brother said, "No." When I wanted to close the door, he suddenly pushed the door very 3and came into our house. He took out a knife and ordered me to tie up my brother's hands with a rope(绳子). I tied up his hands in a special way so my brother could untie himself easily. The man then tied my hands up and locked4 of us in the kitchen.
Soon, he went upstairs to look for money. I taught my brother to untie the rope on his hands. He then untied me. It was lucky that the man forgot to lock the kitchen window. We got out of the house 5 the kitchen window and went to the nearest pay phone to call the police. Soon the police came to our house and the man was caught. I should stop my brother from opening the door to strangers. I learn a lesson on safety.
