Once upon a time, in a big forest, there lived a fast rabbit. The rabbit loved to run and play all day. He had many friends, but his best friend was a big bear. The bear was not fast, but he was very strong.
One day, the rabbit found a sharp spear in the forest. He thought it was fun to play with. He showed it to the bear, but the bear said, "No, rabbit, we must stay away from the spear. It is not safe."
But the rabbit did not listen. He kept playing with the spear. One day, while he was running fast, he tripped and fell on the spear. The rabbit was hurt, and he could not run anymore.
The bear found his friend and tried to help him. But it was too late. The rabbit had not listened to the bear, and now he could not run and play anymore. The rabbit and the bear were very sad, and they knew they should have stayed away from the spear.
