A barking(狂吠的) dog was lying on the hay(干草堆) that the farmer had put down for the cows.
The cows could not eat the hay(干草堆) because they were scared(害怕) of the doy.
“What a selfish(自私的) dog!” said one of them. “He can’t eat the hay(干草堆) himself, but he won’t allow us to eat it either.”
MORAL: We should not prevent(阻止) others from enjoying what we can’t enjoy ourselves.
