Full text of mouse's gratitude in Aesop's fables

The lion fell asleep and a mouse jumped on him. The lion woke up and immediately caught the mouse and ate it. The mouse begged for mercy and said that he would repay the lion's kindness in the future. The lion smiled at it and let it go. Later, the lion was caught by the hunter and tied to a tree with a rope. Hearing the lion's sigh, the mouse ran to bite the rope and let the lion go. The mouse said, "You laughed at me and thought I couldn't repay you for saving my life. Now you should know that I am still useful! " "

The lion said, you are right. Thank you! But can you help me again? The mouse asked, what else can I do for you? The lion said, I'm a little hungry now. Seeing the mouse puzzled, the lion opened his mouth and leaned against the mouse. The mouse suddenly realized, and quickly said, wait a minute, tell the truth first, and I will die soon. Last time you didn't eat me, this time I saved you. We are even. How can you eat me again? Besides, you let me go for a while, and then you wanted to eat me. What's going on here?

The lion smiled and said, I was not hungry last time, but now I am really hungry. Besides, you should know what the law of the jungle means, right?

The mouse ran away before the lion finished speaking. As long as the escaped mice hear someone calling them "mice", they won't get angry. The mouse is very angry: What is a mouse? Are there no villains among those mighty big guys?
