I read The Fox and the Stork, a level 1 from Usborne First Reading.
The fox which loves playing trick and the stork are friends.
One day, the fox invited the stork to dinner.
Then, he poured soup into wide bowls, so the stork couldn't eat.
The next day, the stork invited the fox and played trick.
The fox were very angry. But the stork said, "You tricked me first."
He did that to teach the fox a lesson.
I think we should treat others the way we want to be treated.
