The squirrel jumped up and down on the branch, accidentally fell down, and fell onto a sleeping wolf. The wolf jumped up suddenly, grabbed the squirrel, and was about to eat it. The squirrel begged the wolf:

"Please let me go!"

The wolf said:

"Okay, I can let you go, as long as you tell I, how can you squirrels be so happy? I always feel annoyed, but look at you, you are always playing and jumping in the trees."

The squirrel said:

" Please let me go back to the tree first, and I will tell you from the tree, otherwise I will be afraid of you."

He let the squirrel go. When the squirrel got to the tree, he said to the wolf:< /p>

"You are troubled because you are too cruel and have a bad heart. We are happy because we are kind-hearted and do not bully others.

”

Little story but big truth: If you want to be happy, you must have a good heart!
