你一定也有這樣的朋友，第一次見面就一見如故，說不上來的好默契、互相幫忙照顧彼此！
獅子與老鼠就是這樣的一對好朋友！有次牠們翻開了本故事書，內容寫著：『好久好久以前在草原上的獅子睡著了，有隻老鼠跳到了牠身上。獅子猛然站起來，把牠抓住，準備吃掉。老鼠請求饒命，並說如果保住性命，必將報恩，獅子輕蔑地笑了笑，便把老鼠放走了。不久，獅子真的被老鼠救了性命，原來獅子被一個獵人抓獲，並用繩索把牠捆在一棵樹上。老鼠聽到了他的哀嚎，走過去咬斷繩索，放走了獅子。』獅子和老鼠闔上了故事本，面面相覷笑的非常開心，原來他們在很久很久以前就已經認識了呢！
You must have friends like this, who feel like old pals from the very first meeting, with an unexplainable sense of harmony and mutual care!
Lion and Mouse are exactly that kind of great friends! One day, they opened a storybook, and the story inside went like this: "A long, long time ago, on the grasslands, a lion fell asleep, and a mouse hopped onto him. The lion suddenly woke up, grabbed the mouse, and was about to eat it. The mouse begged for mercy and promised to repay the kindness if its life was spared. The lion chuckled disdainfully and let the mouse go. Not long after, the lion's life was indeed saved by the mouse. It turned out the lion had been captured by a hunter and tied to a tree with ropes. The mouse heard its cries, went over, and gnawed through the ropes, setting the lion free." Lion and Mouse closed the storybook, exchanged smiles, and were very happy. It turned out they had known each other for a very, very long time!
