The donkey and the monkey

The donkey was celebrating his birthday. Many animals were taking part in the donkey’s birthday party. When it was the monkey’s turn to enter, the donkey didn’t allow the monkey to come in, and the monkey got upset and went home. Three days later it was the monkey’s birthday. The donkey was also taking part in that party. When it was the donkey’s turn to come in, the monkey didn’t allow him to enter. The monkey treated the donkey in the way the donkey had treated her.
Here is the conclusion: You should treat your friend in the way you want your friend to treat you.
