Once upon a time, there was a little boy named Jack. Jack had a toy with a long cord. He loved to pull the cord and watch the toy go. One day, Jack saw a door that was close. He wanted to see what was behind the door.
Jack pulled the cord and tried to open the door. But the door did not open. Jack tried again and again. He was very persistent. He asked his friend, Tom, to help him. Tom said, "Are you sure we should open the door?"
Jack and Tom pulled the cord together. Finally, the door opened. But behind the door was a big, scary dog! The dog barked loudly and chased Jack and Tom. They tried to run away, but the dog caught them.
The dog bit Jack's toy and broke the cord. Jack was very sad. He should have listened to Tom and not opened the door. Now, Jack's toy was broken, and the dog was still angry. The end.
