The work of an unusual guest

Unusual guests After school, Beibei watches TV at home alone. Suddenly, the telephone rang. She picked up the receiver and heard her mother's voice. Her mother told her to stay at home and go home in ten minutes. Beibei answered the phone and continued to watch TV. After a while, there was a bang outside the door. Beibei hurried to open the door, but it wasn't her mother who appeared in front of her ... Beibei looked at the stranger in front of her and didn't panic, but calmly said to the stranger, "Who are you looking for?" The stranger answered unhurriedly, "Oh, I'm your mother's friend. Is your mother not here? " The stranger looked into the room as he spoke. "She's not here, otherwise, you sit down for a while and mom will be right back." Of course, the stranger agreed and followed Beibei to the room. Beibei is a very clever child. She opened the door and window and said to the stranger, "I'll call my mother and ask her to come back early." The stranger is a little scared. He was worried that Beibei would call the police, so he stared at Beibei on the phone. "Mom, when will you come back? Oh, here we are. By the way, there is an uncle at home. Say he's your friend. Hurry upstairs! Just call dad back. He is a policeman. He is very busy all night and seldom comes back to see us. " When the stranger heard Beibei's words, he was startled and wanted to start early, but the doors and windows were open and people kept going upstairs and downstairs. The stranger had to play along and said to Beibei, "Hey, just ask your mother to call me. I have work to do. I will go back first! " "Beibei smiled. She thought, this uncle is really stupid. Is he still worthy of being a thief? Ha ha! She said to the stranger, "well, then go home." I'll ask my mother to call you. " The stranger laughed bitterly twice and just wanted to take out the rope and tie Beibei. Suddenly, a fierce cry came from behind, "Don't move, police!" " "The stranger suddenly turned his head and saw not a policeman, but a group of policemen. Beibei smiled proudly: "You can't think of it! I just called the public security bureau. They are very smart and understand me. And I left the door open so that the police uncle could take you down quickly! " With that, the stranger was taken away by the police. The captain gave a thumbs-up and said to Beibei, "You are great!" Beibei smiled happily. From then on, the thief's family never dared to play the idea of Beibei's family, because there was a little hero in their family.
