牛和狗

一头牛和一只狗同时为一个农夫工作。

一天, 狗骄傲地说着;‘我是多么重要啊!白天我在牧场看护家群,晚上我看家。而你呢…..?”

“我?我怎么啦?“ 牛反问。

“你只会犁地或是拉扯。”狗不懈地说。

“是的。你说得没有错,”牛回答道。“但是如果没有我犁地,你看护什么呢?”

The Ox and the Dog

An ox and a dog serve for the same farmer.

One day the dog arrogantly says: “How grand I am! In the daytime, I watch out for the cattle in the meadows; at night, I guard the house. But you…”

“Me? How about me ?” the ox says

“You can only plough or draw a cart,” the dog slightly says.

“Yes. It’s true,” the ox says. “But if I don’t plough, what do you guard?”
