从前，有个叫彼得的牧人，他每天都会把他的羊群赶到牧场去放牧。
有一天，他发现有几只野山羊混在了他的羊群里。
傍晚时分，彼得把所有的羊都赶回了羊圈。
第二天，一场大暴风雨来临，彼得无法将羊群带到牧场去，只好在羊圈里饲养它们。
他对自己的羊只给了一点点食物，刚刚足够让它们不饿死。
但是，为了让那几只野山羊留下来成为他的羊，彼得给了它们很多的食物。
雨停后，彼得又带着所有的羊去了牧场。
当他们来到山下的时候，那些野山羊全都逃跑了。
彼得非常生气，他指责野山羊忘恩负义，得到了特殊照顾却还要逃跑。
野山羊停下来回答说：“正因为这样，我们才更要小心。你对我们这些昨天刚来的特别好，而对你的老朋友却不那么关心。这让我们觉得，如果有新的野山羊来，你一定会再次冷落我们而去喜欢他们。”
这个故事告诉我们，那些喜新厌旧的人的友谊是不可信的。
因为他们即使和你交往了很久，一旦有了新朋友，就会忘记旧朋友。
Once upon a time, there was a shepherd named Peter. Every day, he would take his flock of sheep to graze in the pasture.
One day, he found that several wild mountain goats had mixed in with his flock.
In the evening, Peter drove all the sheep back to the pen.
The next day, a big storm came, and Peter couldn't take the flock to the pasture. He had to keep them in the pen instead.
He gave only a little food to his own sheep, just enough to keep them from starving.
But to make those wild mountain goats stay and become his own, Peter gave them lots of food.
After the rain stopped, Peter took all the sheep to the pasture again.
When they reached the foot of the mountain, all the wild mountain goats ran away.
Peter was very angry. He accused the wild mountain goats of being ungrateful, for running away after receiving special treatment.
The wild mountain goats stopped and replied, "That's why we have to be careful. You were especially kind to us who just arrived yesterday, but not so much to your old friends. This makes us think that if new wild mountain goats come, you will neglect us again and favor them."
This story teaches us that the friendship of those who love novelty and hate the old is unreliable.
Because even if they've known you for a long time, once they have new friends, they'll forget about their old ones.
