A lion came to a small stream to drink water. At the same time a hog also came there to drink. Each one of them claimed to drink first. The wordy duel between them became a big fight. There was a fierce fight and both of them became tired. When they took rest for a while, they saw two vultures waiting for eating the defeated. So they came to a conclusion that it would be better to avoid fighting and became friends than to fall a prey to the vultures. They became friends and both of them drank the water and went off peacefully. 
So we should not fight amongst ourselves.
