Once, there was a big mattress. It was very soft and cozy. A cat and a dog both wanted to sleep on the mattress. They knew they needed to share, but they did not want to.
One day, the cat jumped on the mattress first. The dog felt guilty because he wanted to sleep there too. So, the dog barked loudly to scare the cat away. The cat ran away and hid under a table.
The dog slept on the mattress, but he still felt guilty. He knew he needed to share with the cat. The next day, the dog let the cat sleep on the mattress. They both learned to share and became good friends. They both slept on the mattress together and were happy.
