Once upon a time, in a cozy little house in the forest, lived a family of bears. Papa Bear was very big, Mama Bear was of medium size, and Baby Bear was small. One morning, Mama Bear served the most delicious porridge for breakfast, but it was too hot to eat, so the three bears decided to go for a walk in the forest while it cooled down.

After a few minutes, a little girl named Goldilocks arrived at the bear's house and knocked on the door. Finding no answer, she opened the door and went into the house without permission.

In the kitchen, there was a table with three bowls of porridge: a large one, a medium one, and a small one. Goldilocks, who was very hungry, thought the porridge looked delicious.

First, she tried the porridge from the large bowl, but it was too cold and she didn't like it. Then, she tried the porridge from the medium bowl, but it was too hot and she didn't like that either.

Finally, she tasted the porridge from the small bowl and it was just right! It was neither too cold nor too hot, it was perfect! The porridge was so tasty that she ate it all up without leaving a bit.

After eating the bears' breakfast, Goldilocks went to the living room. There were three chairs in the room: a big one, a medium one, and a small one.

First, she sat on the big chair, but it was too high and she didn't like it. Then, she sat on the medium chair, but it was too wide and she didn't like that either.

Then she found the small chair and sat on it, but the chair was fragile and broke under her weight. Looking for a place to rest, Goldilocks went up the stairs.

At the end of the hallway, there was a room with three beds: a big one, a medium one, and a small one. First, she climbed onto the big bed, but it was too hard and she didn't like it.

Then, she climbed onto the medium bed, but it was too soft and she didn't like that either. Finally, she lay on the small bed, which was neither too hard nor too soft. It felt perfect! Goldilocks fell fast asleep.

After a while, the three bears returned from their walk in the forest. Papa Bear immediately noticed that the door was open.

"Someone has been in our house without permission, sat in my chair, and tasted my porridge," said Papa Bear in a voice filled with anger.

"Someone sat in my chair and tasted my porridge," said Mama Bear in a slightly annoyed voice.

Then, Baby Bear said in his small voice, "Someone ate all my porridge and broke my chair." The three bears went up the stairs.

Upon entering the room, Papa Bear said, "Someone has slept in my bed!" And Mama Bear exclaimed, "Someone has slept in my bed too!"

Baby Bear cried, "Someone is sleeping in my bed!" and began to cry uncontrollably.

The crying of Baby Bear woke up Goldilocks, who was very scared, jumped out of the bed, and ran down the stairs.

The three bears watched in surprise as Goldilocks fled their home, running into the forest as fast as her little legs could carry her.

They looked at each other in disbelief, stunned by the intrusion and the mess she had left behind. But even though they were upset, they felt relieved that she was gone.

From that day onwards, the three bears made sure to lock their house whenever they went out for a walk. And as for Goldilocks, she learned a valuable lesson that day about respecting other's property.

They continued to live happily in their little house in the forest, knowing that they were safe from any future intruders. As for Goldilocks, she never ventured far from home again, always remembering the scary encounter with the three bears.
