Once a goat was grazing on the grassy slope of a hill near a stream. It decided to taste the grass on the hills across. A narrow log served as a bridge across the stream. While crossing the bridge, it saw another goat coming from the other side. The bridge was so narrow that only one animal could cross the bridge at a time.
The first goat said to the other, "let me pass first".
"You let me pass first" snapped the other goat.
They started threatening each other and finally got into a terrible fight, so savage, that they lost their balance and fell into the stream.
The other goats grazing on the hills saw this spectacle and learnt a lesson.
After few days, two other goats faced the same problem. They happened to be on the bridge at the same time facing each other and unable to move further.
One goat said to the other, "I will sit down and you can step over my body."
"Thank you. Next time, I'll sit down and let you cross first."
Thus, both of them were able to cross the bridge safely.
